Demis Hassabis, co-founder and CEO of Google DeepMind, described artificial intelligence as “overhyped in the short term” but “underappreciated in the medium to long term.” He predicted a “new golden era of discovery” across medicine, energy, and science over the next 10 to 15 years.

The bubble warning from inside the machine

Hassabis flagged the risk of an “over-correction” in AI startup valuations. Massive amounts of capital are flowing into pre-revenue AI companies, and the investment landscape swung rapidly from skepticism to obsession.

Hassabis has been voicing similar concerns since 2024, consistently emphasizing that achieving true artificial general intelligence, or AGI, requires additional breakthroughs beyond simply scaling up existing models. He places the AGI timeline at approximately 2030, give or take a year, based on remarks he reiterated during talks at Stanford in June 2026.
