Closing in on some ageism inflection points, I find I have the opposite problem: everything is still interesting! Maybe more so: things I thought were boring at 20 are things I now know more about the relevance of. And the thing that's terrifying is knowing I won't have time to learn it all.
Paradoxically, this does have the side effect that I'm more skeptical of learning some new ways of doing the same thing, preferring to prioritize new learning for actual new capabilities vs different arrangements of the same deck chairs. I see that behind some of the inertia in my experienced cohort -- just-in-time can be reasonable approach to picking up specific tech.
OTOH, I've certainly worked with people who are aggressively disinterested in picking up anything new, even when offered the chance to do so on the job, and that's certainly no fun to work with. Or manage.
