Our dependence on internet services of a few key tech companies leaves us vulnerable to cloud failures, bugs and more, experts say

It happened again. A power outage hit a datacentre in London, and things cascaded from there: multiple banking services faltered, court hearings were put on hold and patients reported temporary glitches on the NHS app.

The datacentre in question was in Google’s europe-west2-b zone, one of more than a dozen “zones” that the US search giant maintains in Europe to service its clients.

We examine claims and counterclaims about the risks and calls to slow down the pace of AI development

There have been some shocking claims in recent days about AI safety: we face a 10% chance of doom; AIs are worse than nukes; a “botnet” threatens the entire internet; it’s all a big tech psyop.

Below, we look at six claims and reactions to them.

Relocation coincides with proposed laws that opponents say would entrench power of US tech billionaires in country

Dozens of protesters converged on Peter Thiel’s mansion in Buenos Aires this week after a congressional session raised questions about the billionaire’s presence in the country.

In white masks, they held signs saying “Peter Thief” and “No to the Peter Thiel law” in front of the wrought-iron gates of the $12m (£8.9m) residence, which Thiel bought in April as he moved his family to Argentina.

Observers express concern that the division has lost its independence and commercial reality has taken over

When Sir Demis Hassabis said AI had brought the world to a “pivotal moment in human history” last month, he knew another big change was imminent.

This shift was closer to home. The Nobel prize-winning head of Google DeepMind, Google’s AI unit, announced this week he was relinquishing his day-to-day duties as chief executive and becoming chair. He is also taking on the role of chief scientist at DeepMind’s parent, Alphabet.

Investors scramble to make sense of a shock Chinese challenge to the dominance of western chipmakers

Even for the rollercoaster world of AI, last week was particularly volatile as investors scrambled to keep up with developments that threatened the dominance of the largest western chipmakers.

It began with a double whammy. On Monday, the Chinese memory chipmaker CXMT floated on the Shanghai stock market, soaring by 466% in value to 3.3tn yuan (£365bn).

Does a thought-experiment about US ascendancy in the technology say as much about AI jitters as it does about the reality?

It’s 2031 and the US and China are about to tear Europe into pieces.

The US ploughed vast sums into datacentres and the EU did not. China built robots and Europe did not. American companies “restructured” their workflows around AI and fired people, while EU workers went on long lunch breaks and handed over administrative tasks to the AI model Claude.
