I feel we are going a bit off topic here, but I’ll say that you have to deal with a lot of frustrating situations in these large organizations, so it tends to wear you out. Startups, in my experience, are more fun if you are a person who thrives off being productive. Still to this day, I look fondly at my “early startup employee” phase, I have never been able to be so fulfilled in my professional life ever since, despite my compensation going up 10X+ from those days.
Plus, a lot of people on HN routinely and proudly state how they would never want to work for companies like Meta or Google for ethical reasons, so there’s that too.
