I think the author is justified in his thinking here. It's a large time investment to build skills to a certain level. To just set aside those hard earned skills, and not know when or if you'll be able to utilize them again is demoralizing. Especially if you enjoyed working with said technologies.

I can understand that, but that's kind of the opposite problem. You invested time and practice, now you want to benefit from it, versus you are currently not investing in the same skill, which degrades it over time. The latter seems overblown to me personally. Sure, to get warm again with some specific tech takes some effort, but it doesn't get lost.
