An investment analogy can be "Core & Explore" portfolio of skills with pareto distribution (say 80% Core, 20% Explore).

The core skills are those that have stood the test of time over multiple decades (OOP, FP, Operating Systems, Distributed Systems).

The "Explore" portfolio is essentially venture capital like bet on new tools/frameworks/languages. Most of the venture bets will fail, but few of them will have exponential returns where you will get ahead of the rest of the market or discover early that your side-project/prototype is very valuable in the market (e.g. ML, Cloud services, etc).
