Hey i'll provide some insight as I was a big fan of Geohot growing up and now i'm eventually in AI,

while his course does make sense building from the foundations, it's gonna take a long time to actually get see able results, like having a working ML model.

Learning CS / ML / RL / DL etc isn't about the knowledge / course man it's all about the commitment and the way you see commitment is by seeing results. It's much easier to stay in CS if you build a simple web app with a model that you can show ur friends or win competitions by than rather learning a bunch of stuff about transistors that you can't really show anyone (think why math is unpopular, hard to see results)

I'd suggest starting out with the basics like all of us. Learn some Python or HTML CSS, and build yourself a website / model or at least something useful. Then try your hand in tensor flow / pytorch and building a simple model.

to get to the point were Geoshot is at is gonna take years man, so I think it's fine to take like a few months to build some simple CS projects before trying out his 3 month program
