It's funny, I see the opposite and I would only trust a senior engineer with conducting such a wide-reaching change. I would be more likely to hire a senior engineer who might now be able to effect such change.

Exactly. AI opens up a massive development frontier of projects that were simply impossible before. It does differentiate though. In the old world most "software engineering" work had nothing to do with software engineering so being highly skilled, educated, and experienced in software engineering made very little difference in compensation, position, promotion, etc. "software engineer" isn't a real thing anyway. coding is a secretarial job. you have to move beyond the mindset that coding is doing something useful. it's not. it is a means to an end and now better means exist. if you want to be an engineer you have to think in terms of systems engineering and building systems that deliver defined externally testable capabilities. in a few more years the idea of reading and writing source code will seem as absurd as reading and writing asm seems today.
