What do you mean? Chia miners will be forced to continually expand capacity, otherwise they will be left behind by difficulty adjustment as other miners expand capacity instead. Chia does only one thing: replace $1000 spent on electricity with $1000 spent on SSD manufacturing. It’s unclear which one is worse for the environment, but I think it’s likely that SSD manufacturing is worse, given the (real) mining and toxic chemicals involved.
