Tech billionaires have raised more than $340m to defeat Prop 40, a one-time 5% wealth tax that will fund healthcare and education

Tech billionaires have been dumping hundreds of millions of dollars into the fight against a wealth tax in California. They’ve raised more than $340m, and the campaign they’re funding is spending more than $1m a day to defeat the measure, according to state financial disclosures.

With the election less than a month away, those funds are being spent at a stepped-up pace. During the first 19 days of September, according to the most recent campaign filings, the opposition campaign plowed through at least $21.2m to fight the billionaire tax – surpassing $1m per day. Voters are being inundated with robotexts, mailers and advertisements that warn a tax on billionaires would “expose all Californians to higher taxes”, as one ad reads.

Report comes two days after former employee quit claiming company’s models could cause human extinction by 2030

Criminals, state-sponsored groups, spyware vendors, scientists and propagandists have attempted to use Anthropic’s powerful artificial intelligence models to design missiles and bombs, create deadly pathogens and surveil dissidents, according to a threat intelligence report the company published on Thursday.

“The cases we share here aren’t typical misuse, but rather examples of the most notable and novel threat activity we’ve identified to date,” Anthropic wrote in its 154-page report. “We’re publishing this work because we believe we have a responsibility to disclose malicious misuse of our services.”

Former Anthropic employee Jacob Coxon said AI will become ‘superhuman systems’ that can cause human extinction by the end of the decade

Ted Cruz, a republican senator from Texas, said in an interview on ABC’s The View, that AI posed a “catastrophic risk” and that he “read that whole tweet thread that that developer put out. It was highly concerning.

Lawsuit filed by dozens of employees says people who took maternity or disability leave were disproportionately selected for layoffs

Dozens of Meta employees have sued the social media company over claims that it used artificial intelligence tools to tag workers for mass layoffs. The workers allege that those AI tools targeted them after they asked for protected or maternity leave or disability accommodation.

The lawsuit, filed Monday in federal court in the northern district of California, points to Meta’s workforce reduction of about 8,000 employees earlier this year. Meta is the parent company of Facebook, Instagram and WhatsApp. The suit alleges that Meta used a “constellation of internal artificial intelligence systems”, including AI performance ratings and keystroke- and activity-monitoring data, to pinpoint who to lay off.

Manny Rutinel’s House campaign draws millions from big tech as pro- and anti-AI factions spar over regulation

Political groups funded by top tech executives have been homing in on one local race in Colorado, as the state’s Democratic primary vote gets under way on Tuesday.
