OP here, good points.

Your comment on Intel is correct, but it's also true that TSMC could invest billions into advanced fabs because Apple gave them a huge guaranteed demand base. Intel didn’t have the same economic flywheel since PCs/servers were flat or declinig.

That's a good clarification on Amazon, running on commodity hardware with competitive pricing != competing on price alone. It would have been better to clarify this difference when pointing out that they're trying the same commodity approach in AI.

Amazon is doing exactly everything except competing on price and they don't run commodity hardware either. They're even developing their own chips. Sure they have "commodity" GPUs and CPUs in some lineups, but they also have Graviton.

If you get something this mundane wrong from the start I don't know how I could trust anything else from the post either.
