Both times I spent time I could ill afford to spend replying, answering the questions or saying I'm happy to chat (with caveats about my expertise) & offering potential times.
Neither replied to me.

Trousers which are the right length.
Pros of Japanese trousers:
1) they're the right length, without me having to chop inches of material off the bottom,
2) they fit both my thighs and waist (usually trousers which go around my quads fall off my waist).
Cons: I need a size large...
This sounds similar to Adam Moss's AI Cosmologist: arxiv.org/abs/2504.03424 .
