It's not wrong the vast majority of the time. In fact, it's petty damn good at explaining principles and giving feedback on code, but it doesn't read minds, and so it can be wrong sometimes. It sometimes tells you you're wrong while explaining the exact same thing you just told it back to it.

People can be wrong, too. I just saw a teacher explain something wrong in my daughter's online school video. She had the right answer but explained it wrong and confused my daughter. I think it's fine to prefer human assistance, but AI is really good at having infinite patience and stepping back and covering fundamentals when you aren't ready to understand a thing.

My point is: however you find the answers you are seeking when confused, keep seeking. Keep asking questions. Keep experimenting.
