I can only partially answer this. Humans cannot sense moisture on the skin, only temperature and tactile (e.g. something on the skin, or moving along the skin like a droplet)

Something that cannot transfer heat would, I assume, feel not like putting a hand in water, but rather something…else?

I have been in a discussion with a colleague all day about the API controversy, instead of working. We have been talking about how Lemmy feels like what Reddit once was; a community of people that have interesting discourse around interesting topics, and not just an endless scroll of low effort posts and lower effort comments like ‘THIS!’, ‘AND MY AXE!’, or ‘I ALSO CHOOSE THIS GUYS DEAD WIFE’.

I think I have been grieving the what Reddit once was for a much longer time than I realised. Lemmy feels like home, one that I haven’t haven’t been able to visit for years.
