I've enjoyed using fish. The biggest thing for me is the autosuggestions, that alone has been a great QoL improvement https://fishshell.com/docs/current/interactive.html#autosuggestions
the problem of making humans and groups more rational hasn't disappeared, and some people might want to pick up the challenge (and perhaps talk to people who were involved in it to rescue some of the conclusions and insights).
I'd think (and encourage) that anyone is welcome to pick up the challenge, regardless of the state of CFAR. More people working on the challenge seems like a great thing to have.
NYC's 2024 winter solstice was my first solstice so I roughly knew to expect things to get sad/dark and then to get more positive after, but I don't recall if there was a slide or description of that in the beginning. my memory feels pretty fuzzy here, so it's entirely possible this was covered and I just forgot!
