My knee jerk is that there are quite a few people who can't or won't snowmobile when needed and ski when needed.

That's where the analogy starts to break a bit. You can't mode switch between skis and snowmobile, but you sure can ai assist/not pretty quickly.

One more quick one - imagine skiers showing up to the snowmobile club hating on snowmobiles and vice versa.

I, for one, have still not properly got a grip on how tech enables this sort of a analogy-breaking reality.

Effing go ski then; there's even a club for that! (rhetorical, not directed at anyone in particular) And shame on me cause I show up to the ski club on a snowmobile with skis on my back.
