Of course you're not going to be as quick as you were at 20 for the rest of your life, but you will get wiser. [Edit: Or maybe just more opinionated? I think I was pretty opinionated when I was young, though] As you get older, you learn metapatterns about the world. You see the things you thought were unique new wisdom, were actually just a fashion. So you get more selective about where you apply the limited resources you've got. If you've seen the hype cycle play out in your life once, you're going to be slower to invest in the next wave. That's natural. I've seen the idea of making things portable by implementing things in a Virtual Machine play out more than once in my life... the UCSD Pascal P Machine, then Java, and Flash, and now WASM. However, I've also learned why each failed, so I still have a strong interest in WASM, despite it seeming to be the latest in a pattern. It's because of the unique nature of its security guarantees that I hold out hope for it. Like I said, you get more selective, not just stubborn. I'm 58, and grumpy as heck about some things, and experimenting in direct manipulation of Abstract Syntax Trees for fun as a diversion for now. Once I get my new glasses, and can get about the world again, it's back to learning C and working on MSTOICAL a typed forth variant.
