It also requires a level of maturity, clear thinking, self-starterness, and independence that is hard to come by without a proven track record and experience.
My advice is for the median/average SWE and HNer, not for the truly exceptional.
Spending a 7-10 years in a hub and then going remote first is the best path because you build the network you need to get referrals to vouch for you as a remote-first hire well as the track record needed to go remote-first.
Its also nothing new; new grads gravitated towards these hubs anyway. Previously, they would settle down in the burbs. Now they're migrating anywhere in the US.
