“I think fusion and solar are the two that I would bet on.”

Demis Hassabis, interviewee 23 July 2025 Transcript for Demis Hassabis: Future of AI, Simulating Reality, Physics and Video Games (#475) (Lex Fridman)

Prediction Technology

Asked whether it would be nuclear fusion, Demis Hassabis said he thinks fusion and solar are the two energy sources he would bet on.

Resolved true The record shows it happened or was so.

Prediction: Statements about events outside the person's control, checked once they fell due: did they come true?

What would count as true or false

This is a statement of personal opinion with no horizon. It cannot be tested as a forecast of which energy sources will win, so judge it on whether Hassabis expressed this view. True: the interview transcript or recording from about 2025-07-23 shows that, when asked about fusion, he named fusion and solar as the two energy sources he would bet on. Mostly true: he expressed substantially this view but the wording differs in a minor way (for example, he named them as his favourites rather than as bets). Mixed: he named only one of the two, or named them alongside other sources equally. Mostly false: the transcript shows a materially different position, such as calling fusion and solar promising while declining to bet on any. False: the transcript shows he did not name fusion and solar as his preferred bets, or named different sources.

    “but what, what is the main source of energy, uh, in like 20, 30, 40 years? Do you think it's gonna be nuclear fusion?”

    “He discussed Google's turnaround with Gemini, the importance of research culture, and his views on compute scaling, energy (fusion and solar), and the need for abundance.”

Reasoning

A third-party transcript of the Lex Fridman episode dated 2025-07-23 shows Hassabis was asked about the main energy source in 20 to 40 years and whether it would be nuclear fusion (E2). It also records him answering "I think fusion and solar are the two that I, I would bet on" (E1). A separate summary of the episode confirms he discussed energy, naming fusion and solar (E3). Together these match the True criterion.
