I agree. When you truly understand what you are doing even in a field that moves quickly, your knowledge stays at least to some extent valuable. I would claim that this is especially true for the field of AI. While libraries and frameworks will move as quick as the JavaScript ecosystem, the essence will stay the same. The joke here is that "skills" in AI seem to be more like being able to intuitively turn the right knobs to make the AI algorithm do what you want. This "skill" is of course highly dependent on what knobs there are and what algorithm is used. It's like being able to develop AngularJS only. Nobody should expect their skills being valuable after some time regarding frameworks and libraries in a buzzing field like AI. Just look at how much web development changed in the last decade.
