Clojure is simple, is a lisp (huge plus since they are super simple and you gain access to a whole realm of languages), and practical. You can do anything from backend to frontend dev with it, and the philosophy and community are lovely.
Scheme is less practical but easier to start with.
Haskell is the least practical but isdefinitely beautiful and helps you understand things better.
Wtf. It's obviously crashed because of how absolutely unusable and disgusting youtube has become. I used to use youtube for 3 4 hours a day, but in the last year it may have gotten to an average of 20mins. Because you have to sign in to your google account to watch a video, many of videos cant be viewed with a vpn (which is how very large population of the world use youtube) and the overall quality of content has dropped massively, specially with 3/10 videos and shorts being AI slops.
