The H1B debate has a lot of factions, but one thing is clear: AI is going to be replacing some to a lot of entry level knowledge jobs. Even if it doesn't get any better than what we have now, it'll create a pipeline problem where senior engineers are more valuable than ever and we'll have to figure out how to make room for junior engineers so that eventually they can become senior engineers. Given that, it seems prudent to pump the brakes on H1B--which has become a way to get bodies for entry level work (while top talent has shifted to O visas and the like).
