A good teacher does both too, a bad one neither.

It just spits out pre-made answers. How is that a good way to learn programming.

Yes, could not agree more. The number of times in the past where I have started out with ideas but fallen into gumption traps, flummoxed by something trivial is too many to count. “Vibe coding” blasts through that into clear air.

Agree with what you said but even vibe coding can't learn the principles for you: types, data structures, basic algorithms.

There is a wall that you can't break through with vibe coding. I've been vibe coding myself for more than 3 years at this point.
