My issue with these types is... If you really believed this, why not run to Congress and every world government instead of a Twitter post that will be buried in 2 days? If civilization is going to end, why keep your equity? Microsoft, Google, etc for example all know these risks but they don't guide their revenues to reflect that AI will destroy them. Why? Things don't currently add up, and so far it feels like a lot…
Posting something as important (according to them) as this, to Twitter, is exemplary of some kind of delusion that makes me question whether the content of their post is just the same kind of delusion in another form.
Indicative of someone who hasn't touched grass or interacted with enough of a variety of humans in a little too long.
Time will tell. If we don't hear about it again, then they didn't feel strongly enough to take it further.
