Maybe I’m just young, but what field that you work in that you feel it’s worth investing in preventing the need to stay up to date? In my field, I find myself needing to learn so much every week that the idea of learning a new IDE or something every 3 years seems like a drop on the bucket.

I’d argue that rather than resisting change you should embrace it - future-proofing oneself means adopting new technologies proactively and staying ahead of the curve to avoid being left behind, not finding the magical set of tools than won’t ever become obsolete.
