I'm just as baffled. I went to the comments to better understand but I still don't get it.

I've coded on my phone on several occasions. If you use Android, you don't even need a server or a home computer since Termux works really well as it is. It can run node.js and a bunch of other development tools easily. Or you can just ssh into a server with a development environment and do your stuff their (AI or not).
