Semiconductors being what they are, I don't see how a grassroots movement can drive adoption of something that essentially nobody's making. Are there credible RISC-V based replacements for the Raspberry Pi, the STM32 blue/black pill, and the Cortex chips in phones? Honest question, because I'd love to dabble in RISC-V but last time I checked the options were poorly-supported, expensive, and sparse.

  Thanks very much. Some light reading for when the kids are in bed!

Well you've already been able to get a RV espressif esp for a while, wouldn't be surprised if they have several models by now.

  They do. And there's a new, very interesting WCH32V family from some other company too.
