I've worked at two startups, including one YC. Both were acquired by larger tech companies. I was employee #3 at one and rebuilt most of a broken codebase in the other. I got nothing out of either WRT options. I agree with the author on point 4 but I don't think more options are the answer, I should have just asked for a higher salary I would have been better off.

You're making the right call. I'm probably older than you and I've done two startups. My career hasn't recovered from the lost time. Total waste.
Most startups (by startup, I mean "company focused on such rapid growth that VC investment is mandatory") are pure shit. They fuck up your finances, drain your emotional reserve, and (unless you're a founder) often spit you into junior roles that you won't be able to stand after a taste of real autonomy.
If you don't learn much, then you've wasted time. If you do learn a lot (which you can, with a good run as de facto CTO) then you still end up in a junior role, due to your lack of credibility on-paper, for which you're massively overqualified. That's the worst outcome, because you're better off actually being junior if you're in a junior role; overperformance is far more dangerous (in large companies) than underperformance.
