I've worked with fantastic engineers from Argentina, Poland, Ukraine, etc. and since everyone is on Zoom anyway, them being remote makes no difference (this was not the case prior to about 2015 or so, when video conferencing got good enough), and they all adapt to US time zones.
I've seen lots of CEOs announce layoffs and plug how AI is making them so much more efficient, but I think the reality, besides previous over-hiring in general, is that it's much easier to find and utilize high quality offshore talent. I know some managers at Google who say they have drastically reduced junior engineer hiring in the US (and obviously they had layoffs at Google), while still hiring in lower cost countries.
Be careful what you wish for.
