I know Chris well enough from his writing and some conversations that I can vouch that "resume-driven development" is absolutely _not_ his motivation here.
Chris is one of the most thoughtful and insightful engineers I can think of. He has a love of actual programming, but also deeply cares about how programming and technology have an influence on us as programmers and the rest of the world.
Given that, this post is him expressing his interest in learning technologies because they look interesting and potentially useful, but also giving reasons to _keep_ learning over the course of your career rather than getting stuck in a rut.
