We're getting closer. There are riscv chips in the <$0.10 range. https://www.hackster.io/news/wch-launches-a-sub-10-risc-v-microcontroller-while-a-6-90-dev-board-gets-you-started-90b1ffd7490a https://www.hackster.io/news/wch-launches-a-sub-10-risc-v-mi... At some point you get to a weird place where the logic transistors are so small you get some gate count for free just fitting around the pad drivers and pin protection diodes. We're getting pretty rapidly to the ~10k gate count there where a stripped down classic RISC makes sense.
