$250k+ a year means ~$12k monthly salary.
A semi decent apartment in SV will cost you ~$3k
Bills(phone, internet, electricity, etc) another $1k.
If you are married, groceries at least $1k.
Even if we assume you don’t do anything else in life, and you are in perfect health best case scenario would be $6k savings a month or $72k a year.
It would take you 10 years to save $720k plus whatever you make from investments.
That’s not enough to even buy you a house in SV. How are you going to retire?
Unless you assume you will get $250k straight out of college and keep up salary raises for 25 years.
Sure, if you don’t have kids, age with no health problems, never enjoy anything in life, you may be able to retire at 50 in Thailand or Philippines.
