I don't really understand the desire for skills to be in high demand. Obviously, you want your skills to be in demand in some capacity . But putting so much emphasis on whether some tech skill is a winner on a scoreboard can give people the wrong impression about other languages and technologies that appear to either be unpopular or dying. It's reassuring that Java and SQL are still in high demand after all these yea…
In college I didn’t learn Java at all because it didn’t seem very fun. Python did and I learned that. Then Go came along which was easy to pick up. But once you know a general purpose language well, it doesn’t take long to learn another one (maybe not the most performant code right away but that’s what code reviews by peers are for).
