electoral districts should be determined by an algorithm with proven guarantees and it is cruel not to let the theoretical computer scientists design it because they have been waiting their whole lives for an opportunity like this

Before #MSFT offered "Facilitator" in Teams meetings, @dggoldst.bsky.social et al. developed something similar.
People preferred their #statusQuo, but #AI facilitation
- made people more open to both human and #LLM facilitation.
- didn't seem to impact decisions

Survey question: "You completed this task with a [human, Al, none] facilitator. If you were to repeat this task, which would you prefer?"
"Users seem to prefer what they know, whatever it may be"
"Experiencing LLM facilitation seems to yield interest in both facilitators, in a way that human facilitation doesn't."](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:jf4udtyuylqocyyrqdwqoxuf/bafkreiag7xrbcdzfeeyomu33kmzlkqst5edl7cng357czrbu6qgux3rmt4@jpeg)

Every hotel lamp should have three switches. The switch locations should be determined by pretests conducted in dark rooms. Each switch should reverse the light's state, independent of the other two switch positions.

Quick update from Peru
The Incas somehow shaped rocks to have flat faces and precise angles so they fit together with no gaps.
The top of the wall was reconstructed later and has big gaps.
Some things get worse as time goes on.
