Not to mention that plenty of us can probably relate to parents not understanding what we were doing, making the "cut the cable" approach even worse for the relationship. My family didn't take me seriously regarding self-learning anything (especially programming) until someone they seemingly trusted more told them the same things I had been telling them for years. It used to be pretty frustrating to be trying to learn something and be treated like I was just wasting time on gaming. All it did was make me great at doing things under their nose and unwilling to discuss anything I did or was interested in with them. So yeah, teaching your kids boundaries while allowing them to be self driven is probably ideal.
