Wow, looks like lots of interesting talks. Two rewrites in other languages this year. The regex compilation one looks huge. And the search engine and postgres ones both look very useful.

There are always some that differ more than others. I really wonder what the "polyexistential libre/halal" thing is. I remember there once was a talk on how to generalize the different vim-like "modes", instead of just insert/normal he was zooming in and out of various levels of modes; unfortunately I can't find that talk again, does anyone remember what it was called?

(I did find https://emacsconf.org/2021/talks/nangulator/ with the audience comment "This is weirdware in the best sort of way")
