I think coding on a cell phone would be a pain in the ass tho XD But someone running my code on their cell phone could be an exciting thing.

I'm excited people will be able to code on more device types and I always recommend people use replit when they are getting started.

Nit: people will still predominantly use their phones for consumption, even after being able to code on their phones. Consumers will outstrip producers by a large margin until producing is more rewarding than consuming.
