I think high school is too early to be thinking too hard about what is used in industry.

I learned to program with Macromedia Flash, which was big at the time but was completely irrelevant by the time I actually was ready for my career. I don't regret it at all, though—it was perfect for me learning at the time, and taught me the skills that I've used to pick up dozens of different technologies since then.

For education it's far more important to choose technologies that minimize the barrier to entry and allow someone to start learning meaningful skills quickly, rather than forcing them to slog through the instruction manual for an industrial-strength technology before they even understand the basics. We don't apologize for starting a beginner woodworker on a lathe rather than a CNC machine.
