Claim
Since 2018, he has been the lead of Google AI.
Correction

This is outdated. Since April 20, 2023, Demis Hassabis has led Google DeepMind, while Jeff Dean has served as Google's Chief Scientist rather than the lead of Google AI.

Full reasoning

Google publicly announced on April 20, 2023 that it was combining Google Brain and DeepMind into Google DeepMind and that Demis Hassabis would lead the new unit. In the same announcement, Google said Jeff Dean would take on the role of Google's Chief Scientist. Google's current official research profile for Dean also says he is Google's Chief Scientist, focused on AI advances for Google DeepMind and Google Research.

So while Dean did become head of Google AI in 2018, the present-tense claim that he "has been" the lead of Google AI is no longer accurate after the April 2023 reorganization.

Claim
In 2016, the foundation gave $2 million each to UC Berkeley, Massachusetts Institute of Technology, University of Washington, Stanford University and Carnegie Mellon University
Correction

The dollar amount is overstated. At least two of the named 2016 grants were officially announced as $1 million, not $2 million, so the claim that the foundation gave '$2 million each' is incorrect.

Full reasoning

This sentence says the Hopper-Dean Foundation gave $2 million each in 2016 to the listed universities. But official university announcements for two of the named recipients contradict that amount:

  • UC Berkeley's EECS department announced in April 2016 that it received a $1 million gift from the Hopper-Dean Foundation.
  • MIT announced in August 2016 that it received a two-year $1 million gift from the Hopper-Dean Foundation.

Because the sentence says each of the listed universities received $2 million in 2016, and official announcements show at least Berkeley and MIT received $1 million gifts, the statement as written is false.
