Microsoft stock has hit a record high after hiring sacked OpenAI boss Sam Altman and other key figures from the AI firm. The US tech giant, which is a key investor in OpenAI, is the second most valuable company in the world behind Apple. The firm’s market cap on 21 November reached above $2.8 trillion – up $1 trillion since the start of the year. Microsoft chief executive Satya Nadella announced that Mr Altman, who headed ChatGPT creator OpenAI until he was ousted on Friday, would join Microsoft to lead a new advanced AI research team alongside fellow OpenAI co-founder Greg Brockman “We’re extremely excited to share the news that Sam Altman and Greg Brockman, together with colleagues, will be joining Microsoft to lead a new advanced AI research team,” Mr Nadella wrote on X, formerly Twitter. “We look forward to moving quickly to provide them with the resources needed for their success.” Despite his new role, Mr Altman is reportedly keen on returning to his former company following a revolt among OpenAI employees against the board. More than 700 OpenAI workers signed a letter threatening to quit unless the board resigns and reappoints Mr Altman as chief executive. “The process through which you terminated Sam Altman and removed Greg Brockman from the board has jeopardised all of this work and undermined our mission and company,” the open letter stated. “Your conduct has made it clear you did not have the competence to oversee OpenAI.” OpenAI board member Ilya Sutskever said on Monday that he “deeply regrets” his role in Mr Altman’s sacking, adding that he was now working to reunite the company. Following his exit from OpenAI last week, Mr Altman wrote on X: “I loved my time at OpenAI. It was transformative for me personally, and hopefully the world a little bit. Most of all I loved working with such talented people. Will have more to say about what’s next later.” After rumours emerged that he was looking to rejoin his former company after being hired by Microsoft, Mr Altman wrote: “Satya [Nadella] and my top priority remains to ensure OpenAI continues to thrive. “We are committed to fully providing continuity of operations to our partners and customers. The OpenAI/ Microsoft partnership makes this very doable.” Read More Microsoft chief hints Sam Altman may return as OpenAI staff demand board resignation OpenAI staff ‘threaten to quit over ousting of Sam Altman’ Microsoft’s new AI tool cleans up messy backgrounds in video calls

Less than six years after launching in the US, TikTok is now facing a reckoning. After amassing more than 150 million users in the country, lawmakers are now making moves to roll out a complete ban. The biggest ever Chinese tech success in the US is accused of mishandling user data and holding too much influence over Americans, with Montana becoming the first state to sign a bill into law to make it illegal for TikTok to operate there from January 2024. Fears around national security have been countered with questions about censorship, with the Electronic Frontier Foundation describing the prospect of a ban as a “seed of genuine security concern wrapped in a thick layer of censorship”. The US digital liberties group has called on people to “resist a governmental power to ban a popular means of communication and expression”, while the FBI claims Chinese state ties to parent company ByteDance could allow the app to “manipulate content” in order to spread harmful propaganda. The US is not the first major market to consider a total ban of the social media platform, with India issuing a complete TikTok ban in 2020. Other countries and areas, including the EU, have put partial bans in place. Various federal and state TikTok bans are already in place in the US, banning government workers and military personnel from using the app on official devices. This has done little to stem its growth in the US, with TikTok proving to be the most popular app both in America and globally last year with 672 million total downloads. This has helped bring the total number of TikTok users around the world to above 1.5 billion, with only India’s ban nearly three years ago slightly slowing its growth – but only temporarily. Despite the warnings surrounding TikTok, the app is viewed positively by the majority of young users, which may cause the Biden administration to hesitate on ordering an outright ban given younger demographics typically skew towards voting Democrat. TikTok CEO Shou Zi Chew defended the app and its intentions when he appeared before Congress earlier this year. The former Facebook intern downplayed ties to the Chinese government while trying to convince members of Congress that the app is safe for US users and poses no threat to national security. After Montana signed a TikTok ban into law on 17 May, 2023, a TikTok spokesperson said that the company would “work to defend the rights of our users” in all regions.
