Unpopular opinion that throws a wrench into the whole h1b/eb1/eb2 debate. Being a rando sde (even at faang) isn't specialized. We have tpms getting eb1c (the einstein gc) which has now been backlogged for good reason. I think any loosening on h1bs/ebxs etc should coincide with the upping of the requirements to the o1 visa - https://www.uscis.gov/working-in-the-united-states/temporary... but even this can be gamed.
If one quits, nothing says you'll find another one, and you may keep going with one less person.
