Looking at it from the wrong angle. Someone would have to invariably experience it, if it were to happen. You just happen to be amongst the group, possibly. It is highly likely that a species that evolves to develop a certain level of cognitive ability would develop tools which would eventually lead to automation and possible replacement of its biological form. It is either that or extinction through some eventual cataclysm. Intelligence is the only thing which can give a species a fighting chance to avoid all eventualities in the universe. It's either action through intelligent choices, or random luck.

Unlikely. People will earn based on their market value, along with some other factors like negotiation skills, etc. Profits would veyr likely get passed to shareholders.

LOL. AI isn't very good at context. Being at the helm of a business is all about understanding context. AI may help with knowledge synthesis, providing options, estimating outcomes, but it won't help with broader understanding for some time still. Someone is watching that AI, guaranteed. The rest is marketing.
That chart also contains clear errors, doesn't give off a very trustworthy vibe.
