I don’t believe the control problem is solved, but I’m not sure it would matter if it is.
I don't even understand what the proposed mechanism for "rouge AI enslaves humanity" is. It's scifi (and not hard scifi) as far as I can see.
To put it simply, it could outcompete humanity on every metric that matters, especially given recent advancements in robotics.
Again, I wonder why no group of smart people with brilliant ideas has unilaterally imposed those ideas on the rest of humanity through sheer force of genius.
I don't know if this will happen with any certainty, but the general idea of commoditising intelligence very much has the ability to tip the world order: every problem that can be tackled by throwing brainpower at it will be, and those advances will compound.
Also, the question you're posing did happen: it was called the Manhattan Project.
“AGI” has proven to be today’s hot marketing stunt for when you need to raise another round of cash and your only viable product is optimism.
Flying cars were just around the corner in the 60s, too.
