There are plenty of games that actually use CPU: Microsoft Flight Simulator, Factorio, Stellaris, Total War, pretty much any city simulator game, etc. Sure, your average dumb AAA action game won't, but that doesn't mean a good CPU is worthless.
1 RPM is where a mega base starts. Stronger players can do 20 RPM (yes, a rocket every 3 seconds).
In those conditions, your CPU becomes the limit to the RPM as your game starts to slow down
By the same token you can play virtually any game on a cheap gaming rig. Just put all the graphics on low, run it at 720p and be happy with 20 fps.
Movies can be watched on phones. Does that mean theater screens are pointless?
It’s all state in a machine, and ML is showing us recursion + memory accomplish a lot; why all the generic structure in x86 if we can prove our substrate works just as well with better power efficiency if it’s structured specifically?
Chips aren’t concepts, they’re coupled to physics; simplify the real geometry. I think that’s what Apple is really proving with its chips, and why Intel is trying to become a foundry; they realize their culture can only extend x86 and x86 comes from another era of manufacturing.
I got into tech designing telecom hardware for mass production in the late-90 and early-00s. I just code now but still follow manufacturing, and have friends that work in fabs all over; this is just sort of a summary of the trends we see shrug emoji
