If we rebuilt math education from scratch today, what would it look like?

I’ve been thinking about how math is taught and it feels like we’re not really using the tech we have today (AI, interactive simulations, real-time feedback, etc).

What would a truly modern way of learning math look like if it was built from scratch today?

Not just videos or problem sets — but something more interactive, maybe even personalized or visual in a deeper way.

Curious what ideas or experiences people here have had — what worked, what didn’t?
