Why are people afraid to learn?

I've read,and even talked to a lot of people on programming-related places about what they are doing, learning etc,they always say some generic begginer project like a Todo app,a snake game, whatever,doing generic stuff doesn't make you a bad programer.

The problem is: this people want to learn programming,and guess what? They where not only basically just using AI,but they were using high level languages - which by itself isn't a problem - they were using library's to do everything! I don't mind,it's actually kind of more efficient to use library's, but they didn't even knew how any of it worked!

Also,they don't want to dwelve into any other areas; they don't want to use other,low level programming languages,or just get out of they're confort zone.
