World's smallest microcontroller looks like I could easily accidentally inhale it but packs a genuine 32-bit Arm CPU (www.pcgamer.com)

I guess maybe we have different requirements, but I built a similar controller using a 68HC05 when I was in college (yes I am that old) and it had plenty of cycles left to burn. This thing is nearly an order of magnitude faster than the microcontroller I used.

EDIT: I will grant you the I/O is pretty limited, but you could also offload some of the work to an external timer/accumulator

I imagine the other factor is the tooling at the chip fabs. When you can make an entire microcontroller that small, for 20 cents apiece, why bother continuing to make less powerful chips? We can just do this now.

Reading the article, they mentioned "medical devices and earbuds" as potential use cases.
