Largely agree, with a bit of clarification. Junior devs can indeed prompt better than some of the old timers, but the blast radius of their inexperienced decisions is much higher. High competence senior devs who embrace the new tools are gonna crush it relative to juniors.
It's like having an early/broken chess engine.
An amateur with a chess engine that blunders 10% of the time will hardly play much better than if they didn't use it. They might even play worse. Over the course of a game, those small probabilities stack up to make a blunder a certainty, and the amateur will not be able to distinguish it from a good move.
However, an experienced player with the same broken engine will easily beat even a grandmaster since they will be able to recognise the blunder and ignore it.
I often find myself asking LLMs "but if you do X won't it be broken because Y?". If you can't see the blunders and use LLMs as slot machines then you're going to spend more money in order to iterate slower.

I guess? I don't really see why that would be the case. Being a senior is also about understanding the requirements better and knowing how/what to test. I mean we're talking about prompting text into a textarea, something I think even an "old timer" can do pretty well.
I've seen a few people I would consider senior engineers, good ones, who seem to have somewhat fallen for the marketing if you look at the prompts they're using. Closer to a magical "make it so" than "build the code to meet this spec, that I wrote with the context of my existing technical skills".
I'm not sure why junior engineers would be any better at that though, unless it's just that they're approaching it with less bias and reaping beginners luck.
