That's my suspicion to.

My issue with this being a 'negative' thing is that I'm not sure it is. It works off of the same hunting / foraging instincts that keep us alive. If you feel addiction to something positive, it is bad?

Social media is negative because it addicts you to mostly low quality filler content. Content that doesn't challenge you. You are reading shit posts instead of reading a book or doing something with better for you in the long run.

One could argue that's true for AI, but I'm not confident enough to make such a statement.

AMD Bulldozer did something like this. Ultraspac T1 had a shared FPU too. There is are a savings there, but neither of these solutions ended up being practically fast. The amount of die space spent on an ALU is relatively low compared to the rest of the CPU, hence why they shared FPUs instread.

We might see it again now that the server world is having an ARM CPU renaissance. But I doubt AMD or Intel will make anything that exotic.
