How would it improve skills?
Does driving a car improve your running speed?
I've found AI handy as a sort of tutor sometimes, like "I want to do X in Y programming language, what are some tools / libraries I could use for that?" And it will give multiple suggestions, often along with examples, that are pretty close to what I need.
No, but it does improve your ability to get to classes after work
I have to stretch your analogy in weird ways to make it function within this discussion:
Imagine two people who have only sat in a chair their whole lives. Then, you have one of them learn how to drive a car, whereas the other one never leaves the chair.
The one who learned how to drive a car would then find it easier to learn how to run, compared to the person who had to continue sitting in the chair the whole time.
