Work pressure might be simmering down worldwide as the holidays approach, but at OpenAI, CEO Sam Altman has declared “code red”. Mr. Altman, 40, stressed the need for the company to improve user experience with ChatGPT by enhancing its speed, reliability, ability to answer more questions, and its personalisation — even if that means holding back other products, according to a report. OpenAI in October reached a valuation of $500 billion, so what could have caused this urgent shift? One answer is Google, which in November introduced its “most intelligent model” yet: Gemini 3.
From a child who experimented with his Macintosh computer to announcing a partnership with Apple decades later, the CEO of one of the world’s most famous tech companies has always juggled both tech and business aspirations.
Samuel Harris Altman, born in Chicago on April 22, 1985, grew up with his younger siblings, two brothers and a sister, in a Jewish family. He lived in Missouri and studied computer science at Stanford University but dropped out in 2005, according to Forbes. Mr. Altman went on to co-found Loopt, a social mapping service designed to help people discover more about their location. He later sold Loopt and became closely involved with Y Combinator and had been the start-up launcher’s president between 2014 and 2019.
Though best known for his work in the generative AI space, Mr. Altman was active in the blockchain sector. He is a co-founder of Worldcoin, a cryptocurrency project introduced in 2021 and launched in 2023 that aims to collect people’s biometric data in exchange for giving them an ID and some digital currency simply for “being human”.
Activists allege that the project was used to harvest biometric data without informed consent from people in poverty-struck regions, while Mr. Altman’s initiative was also publicly criticised by NSA whistleblower Edward Snowden.
OpenAI was founded in 2015 as a non-profit artificial intelligence research company. Billionaire Elon Musk was part of the organisation but left its Board three years later over differences over how to operate the company. Since the introduction of ChatGPT in late 2022, Microsoft has invested billions in OpenAI to leverage generative AI technology for its own products. The two companies — and their CEOs — gradually drifted apart as they became competitors.
Furthermore, Mr. Musk and Mr. Altman’s relationship has soured badly since 2018, with Mr. Musk suing OpenAI multiple times over alleged violations of business regulations, while the ChatGPT-maker claimed it was being harassed by the billionaire who now has his own AI company: xAI.
There were also internal conflicts. In November 2023, Mr. Altman was suddenly fired from OpenAI, with the company noting that “he was not consistently candid in his communications with the board”. Soon, Microsoft CEO Satya Nadella announced that Mr. Altman would join the software giant to lead its AI team. In a surprising turn, however, Mr. Altman returned as the CEO of OpenAI, with Board members Helen Toner, Tasha McCauley, and OpenAI co-founder Ilya Sutskever later being removed. The tech world keenly observed the chaotic series of events, which highlighted Mr. Altman’s influence over his peers. A string of employees left the company soon after, with former researcher Jan Leike claiming that “safety culture and processes have taken a backseat to shiny products”.
In the months following ChatGPT’s viral fame, Mr. Altman faced criticism over OpenAI’s approach to training its AI models, with authors and creators alleging that the company illegally scraped their copyrighted works, possibly from piracy databases, to feed AI models with high-quality information. The New York Times joined the fray as it sued OpenAI over alleged copyright infringements.
OpenAI and Mr. Altman are facing a lawsuit filed by two U.S. parents regarding a far more serious matter. Matthew and Maria Raine in August alleged that ChatGPT helped “coach” their 16-year-old son Adam Raine into dying by suicide. The Raine family said that ChatGPT taught their teenager about various self-harm and suicide methods that he later used to take his life, and that the chatbot reportedly discouraged the child from seeking human support. OpenAI expressed its sympathies and has since rolled out safety settings for children, but intends to defend ChatGPT. Mr. Altman, meanwhile, has defended user freedom for adult users of ChatGPT.
Concerns over child safety caused ripples even as OpenAI moved to redefine its non-profit structure. In October, the company announced that the non-profit was the OpenAI Foundation, while the for-profit was a public benefit corporation called OpenAI Group PBC; the foundation controls the group and their mission is the same, says the company. Microsoft now holds around 27% of the OpenAI Group.
Mr. Altman married his partner Oliver Mulherin in January 2024, and announced the arrival of his son this year by sharing the baby’s photo on the Musk-owned social media platform X. While there were congratulatory messages, the comments on X were also teeming with anti-Semitic and homophobic hate speech.
Mr. Altman does not frequently post about his family on social media, but his personal life made headlines after a family member alleged that he sexually abused her for years when she was a child, and filed a lawsuit against him. In January, Mr. Altman issued a public statement denying all allegations, calling them “utterly untrue” and expressing concern about the woman’s well-being.
ChatGPT recently turned three, with Mr. Altman claiming that the chatbot has more than 800 million weekly users. ChatGPT is unquestionably the chatbot that led the generative AI boom in 2023, with Microsoft and Google following with their own chatbot releases that felt rushed and spewed grave errors as a result of AI chatbot hallucination, shocking long-time customers of these legacy companies.
OpenAI greatly enjoyed its first-mover advantages, with Mr. Altman jetting around the globe to meet world leaders, discuss AI regulation, and explore expansion overseas.
However, Google’s sudden leap ahead presents a new threat for Mr. Altman, who previously exulted in his first-mover advantages. At over 25 years of age, Google is a behemoth that dominates multiple search and online technology markets and platforms. In other words, Google can likely bear larger losses for longer than OpenAI as it promotes top-of-the-line AI offerings and integrates them into products used by billions. Google announced last month that its AI Overviews has 2 billion users every month and that the Gemini app surpasses 650 million users per month.
According to the Internet search giant, its Gemini 3 Pro model beat OpenAI’s recently upgraded GPT-5.1 across a range of key AI benchmarks.
Little wonder, then, that Mr. Altman has reportedly declared “code red” at OpenAI.

Netflix has struck a deal with Warner Bros Discovery to buy the legacy Hollywood giant’s studio and streaming business for $72 billion.
The acquisition, announced on Friday (December 5, 2025), would bring two of the industry’s biggest players in film and TV under one roof.
Beyond its namesake television and motion picture division, Warner owns HBO Max and DC Studios. And Netflix has risen to dominance as a household name ubiquitous to on-demand content, while building of its own production arm to release popular titles like “Stranger Things” and “Squid Game.” The streamer has offered roughly $28 a share — largely in cash — to take over Warner Bros. Studios and the HBO Max streaming operation, outpacing parallel offers from Paramount and Comcast.
The deal came after a frantic, weeks-long auction that reshaped industry expectations and exposed deep fractures between Hollywood power players. Sources indicate a $5 billion breakup fee is included in the proposal, a sign of Netflix’s confidence in the deal’s viability.
The acquisition would be the most significant strategic leap in Netflix’s history. It would bring the studio’s vast infrastructure under the company’s control, including DC Studios, Warner Bros Television, HBO, New Line, and a library stretching from the Harry Potter franchise to the MGM pre-1986 catalog. Analysts describe the studio as a “crown jewel,” one capable of elevating Netflix’s standing beyond streaming and into broader cultural and commercial territory.
Paramount — which bid for all of WBD — has pushed back hardest, warning that Netflix’s dominant market position will face insurmountable antitrust scrutiny. In internal correspondence, the company accused WBD’s leadership of favoring Netflix and raised concerns about management conflicts tied to future roles and compensation. WBD rejected the claims as unfounded.
According to Variety, an anonymous group of A-list producers and directors circulated a letter to Congress urging lawmakers to scrutinise the merger, warning that Netflix’s control over Warner Bros. would “effectively hold a noose around the theatrical marketplace.” Their central fear is that Netflix could sharply reduce the exclusive theatrical window for Warner Bros. films, or sideline theaters altogether in favor of rapid streaming turnarounds. Some insiders claim the proposed window could shrink to two weeks, though sources close to the negotiations insist it would be longer.
The group cited Netflix co-CEO Ted Sarandos’ repeated remarks distancing the company from a theatrical-first philosophy, arguing that the merger risks collapsing essential revenue streams and destabilising long-standing exhibition practices.
Warner Bros. Discovery’s stock jumped to a 52-week high on news of the bid. Now as the deal closes, Netflix will not only inherit a massive library but a global theatrical distribution network that could redraw industry boundaries and spark one of the decade’s fiercest regulatory battles.

Meta is delaying the release of its Phoenix mixed-reality glasses until 2027, aiming to get the details right, Business Insider reported on Friday, citing an internal memo.
The delay from an initially planned release in the second half of 2026 is because the company wants a fully polished device, the report said.
Meta did not immediately respond to a Reuters request for comment on the report.
Meta executives Gabriel Aul and Ryan Cairns said moving the release date back is “going to give us a lot more breathing room to get the details right,” the report added.
The goggles, previously code-named Puffin, weigh around 100 grams (3.5 ounces) and have lower-resolution displays and weaker computing performance than high-end headsets like Apple’s Vision Pro, the Information reported in July.
Mixed reality merges augmented and virtual reality and allows real-world and digital objects to interact.
Meta is expected to make budget cuts of up to 30% for its metaverse initiative, Bloomberg News reported on Thursday.
The metaverse group sits within Reality Labs, which produces the company’s Quest mixed-reality headsets, smart glasses made with EssilorLuxottica’s Ray-Ban and upcoming augmented-reality glasses.

India’s government is reviewing a telecom industry proposal to force smartphone firms to enable satellite location tracking that is always activated for better surveillance, a move opposed by Apple, Google and Samsung due to privacy concerns, according to documents, emails and five sources.
A fierce privacy debate erupted in India this week after Prime Minister Narendra Modi’s government was forced to rescind an order requiring smartphone makers to preload a state-run cyber safety app on all devices after activists and politicians raised concerns about potential snooping.
For years, the Modi administration has been concerned its agencies do not get precise locations when legal requests are made to telecom firms during investigations. Under the current system, the firms are limited to using cellular tower data that can only provide an estimated area location, which can be off by several meters.
The Cellular Operators Association of India (COAI), which represents Reliance’s Jio and Bharti Airtel, has proposed that precise user locations should only be provided if the government orders smartphone makers to activate A-GPS technology, which uses satellite signals and cellular data, according to a June internal federal IT ministry email.
That would require location services to always be activated in smartphones with no option for users to disable them. Apple , Samsung and Alphabet’s Google have told New Delhi that should not be mandated, said three of the sources who have direct knowledge of the deliberations.
A measure to track device-level location has no precedent anywhere else in the world, lobbying group India Cellular & Electronics Association (ICEA), which represents both Apple and Google, wrote in a confidential July letter to the government, which was viewed by Reuters.
“The A-GPS network service … (is) not deployed or supported for location surveillance,” said the letter, which added that the measure “would be a regulatory overreach.”
India’s home ministry had scheduled a meeting of top smartphone industry executives to discuss the matter on Friday but it was postponed, a source with direct knowledge of the matter said. On Thursday, Reuters sent questions related to this topic to the ministry.
India’s IT and home ministries, which are both analysing the telecom industry’s proposal, did not respond to Reuters queries.
Apple, Samsung, Google, Reliance and Airtel did not respond to requests for comment. Lobby groups ICEA and COAI also did not respond.
At this point, no policy decision has been made by the IT or home ministries.
Taking advantage of A-GPS technology, which is typically only turned on when certain apps are running or when emergency calls are being made, could provide authorities with location data precise enough that a user can be tracked to within about a meter, according to technology experts.
“This proposal would see phones operate as a dedicated surveillance device,” said Junade Ali, a digital forensics expert associated with Britain’s Institution of Engineering and Technology.
Cooper Quintin, a security researcher at the U.S.-based Electronic Frontier Foundation, said he had not heard of any such proposal elsewhere, calling it “pretty horrifying.”
Governments worldwide routinely seek new ways to better track cellphone users’ movements or data. Russia has mandated the installation of a state-backed communications app on all mobile phones in the country.
India is the world’s second-biggest mobile market with 735 million smartphones as of mid-2025, where Google’s Android powers more than 95% of the devices, with the rest using Apple’s iOS, Counterpoint Research says.
Apple and Google’s lobby group, the ICEA, argued in their July letter that there are significant “legal, privacy, and national security concerns” with the proposal from the telecom group.
It warned their user base would include people from the military, judges, corporate executives and journalists, adding that proposed location tracking risked their security given that they hold sensitive information.
Even the old way of location tracking is becoming problematic, the telecom group said, as smartphone makers show a pop-up message to users, alerting them that their “carrier is trying to access your location.”
“A target can easily ascertain that he is being tracked by security agencies,” said the telecom group, urging the government to order phone makers to disable the pop-up features.
Privacy concerns should take priority and India should also not consider disabling the pop-ups, Apple and Google’s group argued in its July letter to the government.
This will “ensure transparency and user control over their location.”
