Wait 5 years and your skills are down
In the web front-end world I'd be pretty much a newbie. I don't know any of the modern frameworks, everything I've used is legacy and obsolete today. I'd ramp up quicker than a new junior because I understand all the concepts of HTTP and how the web works, but I don't know any of the modern tooling.
It'll be the same here, the only question is if those that do exercise will be able to command better salaries. I think this is possible but not with the current political climate.
Half the people I work with can't do imperative jQuery interfaces. So what I guess. I can't code assembly.
AI will kill that.
