In a sense having a baby forces you to become a more thoughtful and effecient programmer :)
A) Netflix is an ideal first company in the Silicon Valley circuit because their compensation package is a simple formula of <every other FAANG’s compensation package but in all cash>, which makes negotiating the next place much easier because you’re more liquid already and already know what the total compensation should be - or would balk at any other base salary because the cash portion is so much lower, forcing companies to entire you with more shares than they were prepared to. And B) because you simply made enough money to attempt something else in your life.
tl;dr: your yearly TC doesn't change much at these companies unless you get an actual raise. I don't fully understand the reasoning behind the four year schedule, but AIUI, it does not strongly incentivize sticking around for the full four years unless you assume significant stock appreciation.
