The institute, which focused on long-termism and effective altruism, received a £1m donation from Musk in 2015 to study the threat of artificial intelligence.

Musk had also promoted Bostrom's ideas on his platform X for nearly a decade.

The closure was described by Bostrom as a result of "death by bureaucracy." Nick Bostrom, a Swedish-born philosopher known for his writings on the potential threat of AI surpassing human intelligence, ran a research center at Oxford University.

His 2014 book, "Superintelligence," made him a celebrity among tech elites, including Elon Musk, Sam Altman, and Bill Gates.

Musk tweeted about the importance of the book and the potential danger of AI.

However, the center was closed, and Bostrom resigned.

The closure is a setback for the effective altruism and longtermism movements, which Bostrom has advocated for decades, but have recently faced scandals related to racism, sexual, and financial fraud.

Last year, Eliezer Yudkowsky's former colleague and fellow philosopher Nick Bostrom apologized for a decades-old email in which he made racist remarks, using the N-word and claiming that "Blacks are more stupid than whites." Bostrom, known for popularizing the theory that humanity might be living in a simulation, recently published a lengthy final report on the closure of the institute he founded, the Future of Humanity Institute, on its website.
