I'm also finding that as I begin to tread into greybeard territory... I'm still super interested in learning new things. Actually interested in entire knowledge domains I wasn't before.
What seems to have changed is that I have less patience for, though, is learning ephemeral and arcane ways of doing something I already know how to do.
Learn to use microcontrollers? Sure! Never really dove in there, seems like an opportunity. Timeless mathematical knowledge? Totally game. Another front-end framework? Not really interested, maybe I'll wait and see if it survives 5 years and I can actually find people who can talk intelligently about the problems it solves rather than bearing thought-smell terms like "modern" as a fashionable totem.

Reserve new learning for new capabilities.
