I am still feeling my way through these ideas, but think perhaps of an alternative universe where instead of getting cleverer with instruction pipelining (guessing what the next CPU will ask for and using the silicon to work that out), hardware had just added more parallel cores - so it did not need to guess the next instructions, it just went faster because the instructions were in parallel because we magically solved software and developers. You could have a laptop with 1000 cores on it - simple 32/64 bit CPUs that just ran full pelt. The lack of parallelism drove decisions to take silicon and make it do stuff that was not run everything faster. But to focus on getting one instruction set through one core faster. AI has arrived and found a world of silicon that it by coincidence can use every transistor for going full pelt - and the CPUs we think of in our laptops are using only a fraction of their transistors for full pedal to the metal processing and the rest is … legacy??
