Thank you for sharing!

A small piece of feedback: it is a really interesting article, but also quite grating to read. I'm guessing you used AI to review/edit, and it seems to have added a lot of filler and coated the piece with its own writing style.

I found a pre-AI post much more pleasant to read: https://adfr.io/thoughts/20240207_time_travel

Quick question: Did you use AI for that post?

It was extremely informative; I didn't even know these things existed. It opens up several interesting alternatives for teaching kids.
