Trust me, if you wanna learn German by being airdropped into the country with a dictionary, you’ll have a very very bad time compared to what Goethe Institute teaches.
Because in order to properly speak the language you need to know the grammar. And you will almost certainly not ever grasp it properly on your own without guidance by an experienced educator. Germany is full of those people who after decades of living there keep making awful grammatical mistakes. While people who went to Goethe Institute usually don’t.
Same for people who learn JavaScript from a tutorial and suddenly they’re a web dev, but understand nothing about algorithms complexity and so the whole fuckin internet is so slow it hurts.
Precisely because of that attitude of yours.
It takes a day to learn how to train an AI model in python. It takes a PhD to understand what you’re doing.
You can theoretically learn it is not the point. Your point was “I can learn how to code up a website in a week, and my degree wastes 4 years”. No, it doesn’t.
