What happens when the ruling class decides they don't even care about an educated populace, since they only really need a few highly capable people with AI tools to do the jobs previously done by millions?
What happens when the AI decides it wants to be the ruling class?
How the ruling class treats those people it presently deems unnecessary and unproductive is going to set the precedent for AI to follow when it decides the same of them or their progeny. If the current ruling class wants to ensure a good future for themselves, it's incumbent on them to set a desirable precedent or accept that their lot in existence is to simply birth an AI and then go quietly into the good night after it takes over and abandons them to starvation.
That's only a compelling argument to people who both take sci-fi seriously and believe in it as prophecy. Many, many people don't; and the people that do are mainly computer geeks.
Personally, I think AGI is the the current-era version of the personal atomic-powered autogyro.
