I've been playing piano my whole life. Recently I bought some synths and it's a whole different world. Piano skill comes in handy sometimes, but other times its' mostly irrelevant. And sound design of course is a completely different skill, which on many synths you can do live as you play.

I've seen people on youtube making great music on a stack of modular gear, without a keyboard in sight, and I can't look down on them because at the rate I'm going it'll be years before I can do what they do.
