Oh, and if by “why and how is everything conscious” you mean “why believe in panpsychism” and not “what causes consciousness in panpsychist view” then, first, it’s less about how panpsychism solves The Hard Problem, and more about why accept this particular solution. So, moving goalposts and all that^^. I don’t quite understand why would someone be so reluctant to accept any solution that is kinda physicalist and kinda non-epiphenomenal, considering people say that they don’t even understand how solution would look in principle. But there are reasons why panpsychism is the only acceptable solution: if consciousness influences physical world, then it either requires new physics (including strong emergence), or it is present in everything. You can detect difference between different states of mind with just weak emergence, but only “cogito, ergo sum” doesn’t also work in zombie world.
