The best paying jobs are ones that look inapproachable and are inapproachable. (even if that's for two entirely different reasons). Most people look at surgeons, for example, and go "I could never do that", and their jobs are, in fact, difficult and require lots of training, and the combination of those two factors primes people to be willing to give them a bunch of money. Jobs that look hard but are (compared to appearances) easy also tend to pay pretty well.
But jobs that look easy or approachable are in a much tighter spot. Regardless of how difficult they actually are, people are far less willing to give them large amounts of money. Pretty much all the more artistic jobs fall into this camp. Just because any idiot can open up Photoshop and start scribbling, it doesn't follow that competent graphic design is easy.
Right now, software development is incidentally in the "looks hard is hard" category, because the reason it "looks hard" is entirely divorced from the reason it is hard. Most of the non-tech population is under the obviously (to us) incorrect impression that the hard part of programming is understanding code. We know that that's silly, and that any competent programmer can pick up a new programming language in a trivial amount of time, but you still see lots of job postings looking for "Java Developers" or "Python Developers" as opposed to actual domain specific stuff because non-technical folk look at a thing they know is complicated (software development) see the first thing that they don't understand (source code) and assume that all the complexity in the space is tied up in that one thing. This is the same instinct that drives people to buy visual programming systems and argue that jargon needs to be stripped out of research papers.
The shift over to plain-language prompt engineering won't solve the underlying difficulty of software development (requirement discovery, abstract problem solving), but it does pose the threat of making it look easy. Which will make people less prone to giving us massive stacks of money to write the magic runes that make the golems obey their commands.
