No idea what this guy is talking about. Big tech are only talking about the existential risks to hide talking about the actual very real risks of how the technology will be misused.
I always found those guys annoying - they adopted sci-fi tropes while ignoring decades of data driven work on how to minimize misuse of technology.
It's like a postmodern version of Herman Kahn - overusing data driven models while ignoring the variability that arises from humanity.
Edit: also this article is a submarine piece from the AI Safety Summit in Seoul that was cohosted by the UK and SK, and was a flop [0]
