The web is full of crap. To really learn you need to learn how to learn. Education still matters. Otherwise you’re just a gpt4 prompt monkey.
I’ve found many times in my life where the internet doesn’t know anything about what I’m trying to figure out. Your “just google It” recommendation is destructive.
Now, college / uni plays an important role here. It helps you learn how to learn stuff. If you're already good at learning things (and I mean really, really good), you can skip it. Otherwise, you should at least give it a try. Of course, try to get into a good one.
I only got a bit about skimming and note taking from my high school teachers
