Of course, within ten years half of the listed products will be gone, and replaced with the new hotness. But there are definitely a lot of low-level and high-level concepts you pick up along the way, and what I tell everyone who is learning is that the MORE stuff you try, the better you will be at learning MORE stuff. Every piece you learn about, you'll find another piece later that mirrors, borrows concepts, or shares ancestry, and you'll pick it up twice as fast as the last time.
