Max Tegmark is a Swedish-American physicist at MIT whose research spans cosmology, consciousness, and the future of artificial intelligence.
Max Tegmark holds a professorship in physics at MIT and is a co-founder of the Future of Life Institute, an organisation focused on the long-term risks and opportunities of transformative technologies including artificial intelligence. His academic work spans precision cosmology, quantum mechanics, and the mathematical structure of reality.
His first book for general readers, Our Mathematical Universe (2014), presents his controversial argument that physical reality is fundamentally mathematical — the universe is not merely described by mathematics, it is mathematics. The book received serious attention from physicists and philosophers despite its speculative thesis.
Life 3.0: Being Human in the Age of Artificial Intelligence (2017) is a more widely read work: a rigorous and genuinely balanced survey of the landscape of possible AI futures. Tegmark interviews researchers across the full range of opinion about AI risk and capability, and the book is notable for refusing to take a simple position in either direction. It remains the most careful general introduction to the alignment problem for non-specialist readers.
