do you know those are eligible to work from day one right?
It's of no relevance to the conversation. People here are whining that foreign universities aren't as rigorous as ours and yet more than a third of people getting through US PhD programs are still technically transient foreigners.
I also noticed no one addressed @ey's reference to half the Nobel prizes earned in the US in 2025 going to immigrants. For all the commentary in this thread about "we don't want to compete against others on our home turf" no one wants to confront why we aren't competitive on our own home turf.
Have you ever came across that many super geniuses in real life
I worked with exactly one super genius, and he was not born in the US. I know he was a super genius because he repeatedly bested entire industries of PhDs in an assortment of technologies over his career demonstrating world class breadth and depth. I doubt I'll be blessed enough to ever work with a second one.
Having a PhD isn't a measure of being a genius. On the other hand, being a Technical Leader or Principal Engineer in software at Cisco who can't write a function to deterministically remove an element from a data structure is a solid measure that those people are id--ts. Don't bother trying to make noise about the job requiring higher level engineering skills because most at Cisco never had those either and it's cost Cisco and its customers dearly.
or at least at cisco?
I never worked with a competent manager/director/VP/SrVP at Cisco. Most of the software staff is objectively worse than deadwood in that on average for every hour they "work" they produce a bug load so great each takes many hours to work around. I can't say "fix" because a lot of bugs end up in terminal states repeatedly without actually being fixed. Obviously there are some world class hardware engineers who are extremely bright but I'm not sure any I worked with are true geniuses.
Genius if it has no opportunity or drive is worthless, and most work doesn't require genius. What merely good work requires is more rare than most either know or are willing to admit.
