What his skepticism covers
In his 2024 interview, he expects gradual progress and improving safeguards. He also worries about concentrated control of AI. These are his arguments, not proof that future systems will remain controllable. [1]

What the 2026 material adds
His Dædalus conversation supports open research. At Brown, he warns about systems acting without predicting consequences. Support for development and concern about deployment can coexist. [3] [4]

His role and the dates
Dædalus identifies him as AMI Labs’ executive chairman and a NYU professor, with Meta as a former role. The map still uses his 2024 interview for both axes. The newer sources do not provide an overall catastrophic-risk estimate. [3] [1] [4]
