A huge part of what attracted me to programming was how free and open it was. The fact that literally anyone with a computer could install Python/Javascript/etc for free and create virtually any software they wanted, limited only by their own abilities and determination, was wildly exciting to me. I would say empowering, if that weren't such a cheesy overused term. If you were any good at it, you could get a great job at an interesting company.
Now like you said we're entering a world where anyone with a computer can pay a giant tech company thousands of dollars a year to spin up some agents for them. That's much less exciting to me, and I'm certain I would not enter the field if I were just starting out right now (assuming there even was a junior job available).
We've seen how big tech monopolies treat domains they control like search and social media. They try to extract all of the value, leaving nothing for the individual or common good, and they're quite effective at it. I'm not looking forward to them gatekeeping the field of software development as a whole.
