As Elon Musk, Peter Thiel and their peers have grown richer and more influential, Gil Durán argues they have all but abandoned democracy – and found the perfect government to enable them
In April, Gil Durán was permanently banned from Elon Musk’s X for posting just two words. Durán was responding to a post from the tech company Palantir outlining its 22‑point “technological manifesto”, which praised American “hard power”, western culture and AI weapons, denounced inclusivity and called for compulsory national service. Durán responded: “TLDR: Fascism” (TLDR is short for “too long, didn’t read”).
Durán didn’t break any of X’s written rules, he points out over a video call from San Francisco – so much for Musk’s “free-speech absolutism”. His ban might just have had something to do with his preceding tweet, showing the cover of his new book, The Nerd Reich: Silicon Valley Fascism and the War on Democracy. The book’s central argument is that big tech is no longer our friend, as many of its billionaire owners have seized economic and political control and are steering the fate of the planet towards their own bizarre, apocalyptic visions.

Após o aumento dos preços de iPads e Macs — e até de Apple TVs e HomePods — em decorrência da crise dos componentes de memória, muito foi especulado sobre quando os iPhones poderiam ganhar o mesmo destino.
Alguns acreditam que a Maçã poderá reajustar o preço dos seus smartphones com o lançamento da vindoura linha dos “iPhones 18” — a começar pelos modelos Pro, que deverão ser lançados neste ano juntamente com o “iPhone Ultra”, seguidos, no começo do ano que vem, pelo modelo de entrada e pela segunda geração do iPhone Air.
No entanto, o leaker conhecido como Fixed Focus Digital repercutiu, em uma publicação no Weibo, a possibilidade de a empresa aumentar o preço do iPhone 17 já no dia 10 de agosto (próxima segunda-feira).
O leaker não é a fonte da informação propriamente dita; de fato, segundo ele, “há rumores de que o iPhone 17 aumentará os preços em 10 de agosto”, apontando ainda que “é difícil dizer se vai subir [o preço] ou não.”
Também não é possível confirmar se os rumores fazem referência apenas ao iPhone 17 em si ou à linha atual como um todo — o que é bem mais provável. Entretanto, considerando que o modelo base poderá permanecer à venda por mais tempo do que os iPhones 17 Pro, é possível que apenas ele tenha o preço reajustado — e quem sabe o iPhone Air.
De qualquer forma, caso essa possibilidade se concretize, tal reajuste poderá “amenizar” os aumentos previstos com os “iPhones 18 Pro” — que, na pior das hipóteses, poderão chegar a US$300.

FaceTime Dual Capture is bringing simultaneous front-and-rear camera streaming to video calls in iOS 27, allowing compatible iPhones to show the caller and their surroundings without repeatedly switching between cameras.
The feature expands technology Apple introduced with the iPhone 17 family. Dual Capture already allows the Camera app to record through the Center Stage front camera and a rear camera at the same time. iOS 27 brings a similar capability directly into live FaceTime calls.
During a call, the front camera can continue showing the speaker while the rear camera displays whatever the iPhone is pointing toward. Someone attending a concert can share the performance and remain visible. A parent can show a child playing without disappearing from the conversation. A person asking for technical assistance can remain on screen while directing the rear camera toward the equipment causing the problem.
Dual Capture removes the awkward sequence of switching to the rear camera, showing something, and switching back to continue speaking face to face. Both perspectives remain available inside the same call.
The normal FaceTime camera control changes from a simple front-or-rear choice on supported iPhones. When the caller activates the rear camera, iOS 27 keeps the front camera visible by default.
The main view displays the rear camera feed while a smaller window contains the front camera image. This picture-in-picture arrangement gives the other participant a continuous view of the caller’s reaction, commentary, or explanation.
FaceTime > Start a video call > Tap the Flip button
Tapping the Flip button turns on the rear camera without immediately removing the front view. The other participant begins receiving both perspectives as part of the FaceTime stream.
The caller can disable the front view when it is no longer needed. This provides a conventional rear-camera presentation for situations where the surroundings should occupy the complete image.
FaceTime > Tap the camera view > Disable the front camera
The exact labels and placement may change before the public release of iOS 27 because the feature is still being tested in beta software. Its basic behavior is already established: the Flip control activates the rear camera while retaining the front camera feed.
Dual Capture does not create two independent FaceTime calls. Both images belong to one video stream, so the caller does not need a second account, device, or invitation.
The feature also differs from screen sharing. FaceTime screen sharing transmits applications and interface activity from the iPhone display. Dual Capture transmits live video from two physical cameras.
Apple has limited FaceTime Dual Capture transmission to the iPhone 17, iPhone 17 Pro, iPhone 17 Pro Max, and iPhone Air. Each model includes Apple’s 18MP Center Stage front camera and the Dual Capture capability introduced in the Camera app.
An older iPhone that supports iOS 27 cannot originate a Dual Capture stream. It continues to use the normal option of selecting either the front camera or a rear camera during a call.
Older models can still receive and display a Dual Capture feed when they are running iOS 27. This allows an iPhone 16 or another supported device to see both views transmitted from an iPhone 17, even though it cannot send the same presentation back.
Both participants need iOS 27 for the new FaceTime layout to work as intended. The transmitting device must also be one of the supported iPhone 17-generation models.
This limitation is based on Apple’s official feature support rather than the simple presence of front and rear cameras. Earlier iPhones have camera hardware capable of operating in several multi-camera applications, but Apple has not extended its native Dual Capture implementation to them.
Third-party applications have offered forms of simultaneous multi-camera recording for years through Apple’s developer frameworks. The difference is that iOS 27 integrates the experience into FaceTime, where users can activate it through the familiar camera-switching control.
Describing FaceTime Dual Capture as retro-compatible with the iPhone 17 does not fully explain its relationship with the hardware. The iPhone 17 family introduced Apple’s native Dual Capture recording in 2025, and iOS 27 now gives that existing camera system another purpose.
Inside the Camera app, Dual Capture produces a saved video containing front and rear views. Apple lists support for recording at up to 4K Dolby Vision at 30 frames per second on the iPhone 17.
FaceTime uses the camera pairing for live communication instead. Network quality, bandwidth, device temperature, and FaceTime processing can affect the transmitted resolution, so users should not assume that a call will preserve the Camera app’s maximum 4K recording specification.
The Center Stage front camera also contributes more than resolution. Its square sensor gives the iPhone greater freedom to adjust framing without requiring the device to be physically rotated. Center Stage can help keep the caller positioned inside the smaller front-camera view while the rear camera follows the subject being shared.
That combination makes Dual Capture more useful than placing two untreated camera feeds beside each other. FaceTime can preserve the speaker’s presence while directing most of the screen toward the event, object, or location being discussed.
The feature may require more processing power and energy than an ordinary single-camera call. Running two camera sensors while encoding and transmitting live video can increase battery consumption and device temperature, especially during long calls over cellular data.
Apple has not published separate battery estimates for Dual Capture FaceTime calls. Users planning extended sessions may want access to power and a stable Wi-Fi connection.
FaceTime Dual Capture arrives shortly before Apple’s expected iPhone 18 generation, making it likely to become part of how the company demonstrates the new phones’ camera and communication abilities.
Apple has not announced the iPhone 18 lineup or confirmed its final camera specifications. Compatibility with FaceTime Dual Capture is therefore expected from the software’s “iPhone 17 and newer” positioning, but individual iPhone 18 models should not be treated as confirmed until Apple presents them.
The software release gives existing iPhone 17 owners access without requiring another hardware purchase. That approach also provides Apple with a working FaceTime feature before the next iPhone launch rather than introducing the camera mode and communication interface at the same moment.
Future hardware could improve the experience through faster processors, stronger image stabilization, upgraded sensors, or more efficient video encoding. None of those additions is required for the supported iPhone 17 family, which already contains the camera system needed to transmit both views.
Dual Capture is only one part of the FaceTime update. Apple is also improving video-call quality when the network connection is weak, addressing a problem that becomes especially relevant when two live camera views require transmission. Traditional Chinese support is joining FaceTime Live Captions as well.
The weak-connection improvement may determine how dependable Dual Capture becomes away from Wi-Fi. A feature designed for travel, events, repairs, and outdoor calls needs to tolerate changes in cellular bandwidth without freezing both views or forcing the session to end.
FaceTime Dual Capture remains part of the iOS 27 beta as Apple prepares the public update for September. Apple can still adjust the interface, performance, device requirements, and picture-in-picture behavior before the completed software reaches iPhone 17 owners.

Apple has increased its estimated trade-in values for most current iPhone, iPad, Mac, and Apple Watch models in the United States. The adjustments give customers slightly more credit toward a new device, although some older Apple hardware and several Android phones have moved in the opposite direction.
The updated values are maximum estimates rather than guaranteed payments. Apple calculates the final credit after confirming the model and inspecting its condition. A damaged display, enclosure problems, missing functionality, or an inaccurate description can reduce the amount offered.
Most of the increases are modest, but they arrive across several of Apple’s largest product categories at the same time. Recent iPhones receive between $10 and $25 more, every iPad category listed in Apple’s summary gains value, and several popular Macs receive larger increases.
The revisions also reinforce the role of trade-ins within Apple’s retail operation. Credit can reduce the cost of a regular purchase, be delivered through an Apple Gift Card, or lower payments at the beginning of an eligible Apple Upgrade lease.
Every iPhone 16 model included in the update receives a higher maximum estimate. The iPhone 16 Pro Max moves from $685 to $695, retaining the highest listed value among the affected iPhones.
The iPhone 16 Pro increases from $550 to $560, while the iPhone 16 Plus moves from $455 to $465. The standard iPhone 16 receives the largest increase within the family, rising by $25 from $435 to $460.
These changes narrow the difference between the standard iPhone 16 and the larger Plus model. The Pro models retain substantially higher estimates, reflecting their higher original prices and stronger position in the used-device market.
An additional $10 or $25 will not transform the cost of an upgrade, but it can offset part of a case, charger, AppleCare plan, or storage upgrade. The difference also becomes more relevant for customers comparing Apple’s direct program with a third-party reseller offering a similar amount.
Apple’s iPad adjustments are more consistent. The maximum estimate for an iPad Pro rises from $670 to $690, an increase of $20. The iPad Air moves from $445 to $460, while the standard iPad rises from $220 to $235.
The iPad mini also gains $15, moving from a maximum of $250 to $265. That means every current iPad category displayed in Apple’s trade-in summary receives a higher estimate.
Apple’s direct trade-in values are generally lower than the prices an owner might obtain through a private sale. The program instead emphasizes convenience: the device can be returned at an Apple Store or sent using Apple’s online process, with the credit connected directly to a new purchase.
A private sale can produce a better return, especially for a recent device in excellent condition. It also requires the owner to set a price, find a buyer, manage payment, and handle the transfer independently. Apple’s program trades some resale value for a simpler exchange.
Mac trade-in values receive some of the largest increases, but the category also includes notable reductions.
The MacBook Air rises from a maximum of $485 to $520, adding $35. The Mac mini receives the same increase, moving from $340 to $375. The MacBook Pro changes only slightly, increasing from $685 to $690.
Apple leaves the current iMac estimate unchanged at $355. The Mac Studio receives a larger increase from $975 to $1,045, reflecting the higher value retained by recent desktop configurations.
Older professional desktops move in the other direction. The iMac Pro falls from $325 to $315, while the top Mac Pro estimate declines from $2,090 to $2,045.
That $45 reduction at the top of the Mac range means Apple’s maximum Mac trade-in offer decreases even though several mainstream models receive more credit. The changes appear more closely connected to the resale position of individual product families than to a uniform increase across every computer.
Mac estimates can vary considerably because one model name can cover different years, processors, memory configurations, storage capacities, and physical designs. Apple asks for a serial number before producing a more specific estimate for a Mac.
The Apple Watch adjustments are similarly mixed. Apple Watch Ultra 2 rises from $295 to $305, while Apple Watch Series 9 increases from $120 to $130.
Apple Watch Series 10 remains unchanged at a maximum of $150. The original Apple Watch Ultra falls from $215 to $205, losing $10.
Wearable trade-in values can decline quickly because watches receive frequent updates and are exposed to greater physical wear than many computers or tablets. Battery condition, display damage, case wear, and working buttons can influence whether the device receives the estimated credit.
Apple also accepts devices that no longer qualify for monetary value. Those products can be returned for recycling, including older hardware and accessories that would otherwise remain unused.
Apple accepts selected smartphones from Samsung, Google, and other manufacturers when customers move to an iPhone. The latest revisions are less favorable to several Android devices.
The maximum Android estimate across Apple’s displayed range decreases from $370 to $360. Individual changes vary by model.
The Samsung Galaxy S23 Ultra drops from $230 to $200, a $30 reduction. Google’s Pixel 8 Pro declines from $170 to $165.
Other devices remain unchanged. The standard Galaxy S23 continues to carry an estimated value of up to $125, while the OnePlus 12 remains at up to $200.
Apple’s Android offers are primarily designed to remove friction for people moving to the iPhone. They do not necessarily match the amount available from the manufacturer, a carrier promotion, or a private buyer.
Carrier promotions can advertise considerably higher trade-in credits than Apple, particularly around a new iPhone launch. Those offers commonly require an eligible unlimited plan, a new line, monthly bill credits, or a commitment lasting two or three years.
Apple’s direct credit is easier to understand because it is tied to the assessed value of the device rather than a long carrier agreement. The best choice depends on whether the customer values flexibility, immediate credit, or the largest possible promotional discount.
Apple’s published figures represent the maximum available for qualifying devices in suitable condition. The online estimate is based on the answers supplied before the product is inspected.
After receiving the device, Apple or its trade-in partner verifies its identity and checks whether it powers on, functions properly, and matches the reported condition. A difference can produce a revised offer.
Customers can accept or reject a lower revised value. Rejecting it cancels the trade-in and returns the device, although the payment arrangement for the accompanying purchase may also be adjusted. If the inspected value is higher than the original estimate, Apple says it automatically increases the credit.
The way the credit is delivered depends on the purchase. When a customer pays in full for a new iPhone, iPad, Mac, or Apple Watch, the confirmed value can be returned to the original payment method up to the price of the new product. Any remaining amount can be issued through an Apple Gift Card.
With an eligible monthly payment arrangement, the estimated credit can be applied directly to the new device’s purchase price. Under Apple Upgrade, a qualifying trade-in owned by the customer can reduce payments across the initial lease term. Another device cannot be traded in each time the customer exercises the lease’s upgrade option.
Values also differ between countries and can change without a product announcement. The revised dollar amounts apply to Apple’s United States program, while local market prices, available models, currencies, and trade-in partners determine estimates elsewhere.
Anyone considering an exchange should obtain a fresh estimate shortly before purchasing. Apple requires the trade-in device to arrive within the specified return period and says an online estimate is generally protected for 14 days after the customer receives the new product.

Scientists from the Beijing Institute of Technology have revealed a colloidal quantum dot (CQD)-based infrared-to-visible upconverter that transforms the infrared spectrum into full color, allowing people to ‘see’ the infrared in the visible light spectrum.
The research team behind the novel invention said their upconverter can be used in eyeglasses to improve human vision and for augmented reality (AR) applications. They also reported a successful implantation of an upconverter in mice, opening the possibility of an implantable photoreceptor to repair or improve vision in human eyes.
In a published study detailing the novel, full-color IR glasses, the human eye is “inherently blind” to infrared radiation. Although IR radiation interacts with the retina, infrared wavelengths lack the energy to trigger the photoisomerization of the retinal chromophore that lets people distinguish colors. As a result, humans don’t have visual access to over half of the solar spectrum.
Still, the researchers write, “harnessing this imperceptible radiation is critical, as infrared perception unlocks a vast reservoir of inaccessible information.” For example, this added visual information enables critical functions in other animals, such as navigation in darkness or detecting predators and prey from their heat. Still, they observe that our natural visual-light spectrum vision is “utterly inadequate” to access this information that so many animals rely upon.
In their study, the researchers highlight recent advances in accessing the IR spectrum, including “ocular injectable photoreceptor-binding upconversion nanoparticles” that convert infrared light into visible emissions. Other studies have also evaluated wearable lenses with nonlinear upconversion projecting infrared-transformed visible light onto the cornea and photovoltaic nanowire networks.
Although these approaches achieved some IR sensitivity, the study authors said they remain “fundamentally constrained” to narrow near-infrared (NIR) spectral response. These prior efforts also relied on high-intensity laser excitation that the team notes is “incompatible with natural infrared radiation.” The result is a “mostly monochromatic output” lacking infrared spectral discrimination in full color.
For their new approach, the research team investigated a mercury telluride (HgTe) CQD-based infrared-to-visible upconverter. They note that this material combination leverages the material’s “quantized energy level states” in synergy with a separate, dual-emissive-layer organic light-emitting diode (OLED).
Specifically, the engineered layers captured IR photons in strategically engineered hole-trapping barriers. The team explains that this “allows for subtle differentiation of infrared input by tuning the emitted visible color and luminance” based on infrared wavelength and intensity.
“This upconversion yields a discrimination sensitivity to subtle infrared variations exceeding two orders of magnitude higher than conventional single-color modes, capitalizing on the human eye’s intrinsic superiority in chromatic differentiation over simple luminance contrast,” they explain.
To test their material’s IR upconversion ability, the researchers designed a pair of lightweight (23 grams) semi-transparent wearable eyeglasses. The team said these tests were a success, achieving “high-resolution infrared imaging” derived from the infrared spectral information. However, instead of monochrome, the research team said that data is displayed as full-color visible patterns directly onto the retina, “enabling intuitive infrared vision without obstructing natural sight.”
Although the current version of the full-color, infrared-capable glasses is still in the development stages, the team said the technology could lead to advancements in visual prosthetics, augmented reality (AR), and “navigation under environmental conditions where normal sight is degraded.”
Following the successful validation in mice, the team said their technology could also serve as the technological basis for an implantable new-generation retinal photoreceptor. In that design, the team said an implanted device could transform infrared light into visible light emissions “that stimulate light-sensitive proteins on retinal neurons to bypass damaged photoreceptor cells and potentially restore visual function across both the visible and infrared spectra.”
“By surpassing the evolutionary boundaries of biological photoreception, this technology paves the way for next-generation visual prosthetics, high-fidelity augmented reality, molecularly sensitive substance identification, and robust navigation in degraded visual environments,” they conclude.
The study “Multispectral infrared-to-full-color upconversion expanding human vision” was published in Science Advances.

Apple’s popular MacBook Air is experiencing significant supply shortages, while the company explores turning its upcoming smart glasses and headsets into health and fitness devices, according to reporting from Bloomberg News‘ Mark Gurman in his Power On newsletter.
MacBook Air Hit by Memory Shortage
The global shortage of memory chips, driven by surging demand from AI data centers, has now reached Apple’s highest-volume Mac. Retail sources describe inventory of the MacBook Air as more constrained than they can recall. Online orders through Apple’s site show delivery estimates stretching into late August, with some higher-RAM or customized configurations delayed into September.
The crunch previously affected lower-volume models such as the Mac mini and Mac Studio. Apple has already raised prices on Macs and iPads (including a $200 increase that took the MacBook Air’s starting price to $1,299 in the U.S.) to offset higher component costs. The company is also exploring sourcing memory from Chinese suppliers for devices sold in China and is prioritizing production and sales of the entry-level 14-inch MacBook Pro ahead of an expected M6 refresh later in the fall. Marketing for the back-to-school season has been adjusted, with greater emphasis on the Pro and warnings that the MacBook Air is “subject to availability.” The timing is particularly challenging, as the MacBook Air is typically a strong seller during that period.
Health and Fitness Ambitions for Glasses and Headsets
Separately, Apple is working to position its future smart glasses and headsets as health and fitness devices. The company’s Vision Products Group is hiring a strategic product design leader to “define the future of health, well-being, and fitness experiences across vision products,” seeking candidates experienced in digital health products and sensor-driven features.
Earlier plans to bring similar capabilities to the Vision Pro, including a Fitness+ experience that would use body-tracking technology to analyze movements during workouts, were dropped due to technological hurdles and the headset’s weight. Future lighter glasses could incorporate a range of sensors to track movement, form, posture, and other fitness data without compromising comfort, Gurman reports. These features are not expected in the first-generation smart glasses (anticipated around 2027) but are part of longer-term plans that could complement devices such as the Apple Watch.
These developments highlight ongoing supply-chain pressures in consumer electronics caused by AI infrastructure buildouts, alongside Apple’s continued expansion of its health and wearable ecosystem beyond the Watch and AirPods.
MacDailyNews Take: Lighter Apple smart glasses will enable a huge range of applications. We can’t wait!
The Apple Glasses will be the key as holding up slabs of glass as “windows” is suboptimal. When we’re running in a race, for example, we don’t want to have to hold an iPhone or even glance at an Apple Watch, but with a pair of Apple Glasses constantly overlaying time, pace, splits, etc. it’ll be ideal! — MacDailyNews, September 6, 2019

A Receita Federal anunciou dois novos leilões os quais contam com uma série de dispositivos da Apple que entraram de forma ilegal no país. Distribuídos nas cidades de Porto Alegre (RS) e Salvador (BA), eles somam, ao todo, 16 lotes com pelo menos um produto da empresa.
O órgão, é sempre bom lembrar, não especifica os modelos ou as versões de determinados itens incluídos nos lotes, sendo que alguns deles podem estar usados, vir sem caixa ou até mesmo sem acessórios (isso costuma ser alertado). Ele também não faz entregas.
Dentro dos lotes com produtos da Apple, também pode haver outros itens sendo leiloados, vale notar.
Com 190 lotes (embora apenas 11 com dispositivos da Maçã), os itens desse leilão estão concentrados na Superintendência Regional da Receita Federal do Brasil da 10ª Região Fiscal. Segundo seu edital, as propostas poderão ser enviadas para análise a partir do dia 25 de agosto, às 12h, e serão recebidas até 28/8, às 18h.
As melhores serão selecionadas para participar do pregão online — o qual está previsto para o dia 31/8, a partir das 14h.
