We learned that processor manufacturers love "bugs" that get solved by making them or your code slower giving you incentive to buy a newer one to restore the performance.

This seems unnecessarily cynical. Are you saying Intel/AMD are intentionally crippling CPUs?

I'm not saying Intel intentionally limited CPUs, just that they have intentionally limited a lot of things and lied about it in the past.

Intentionally adding bugs? No. Intentionally making them slower with microcode and other software updates? Yes.
