Does moral cowardice matter in someone teaching about ethics? Yes, just as much as physical cowardice matters for a life guard. (The other way is fine.)
Does he express his ideas and teachings as something that it would be good if people did, but he totally wouldn’t if it causes himself a smidgen of inconvenience? If he didn’t, we now know that he was lying. Which matters if your moral framework cares about truth.
If you have to read his works for some reason, do it with open eyes and try to figure out who and what he is lying in service of.
Not surprised. Making Hype and Criti-hype the two poles of the public debate has been effective in corralling people who get that there is something wrong with the “AI” into Criti-hype. And politicians needs to be generalists so the trap is easy to spring.
Still, always a pity when people who should know better fall into it.
