I have to wonder if some people are just trying to follow the hype. This reads like the "put a cell phone camera on your dashboard to make a car self-driving" approach to reflection.
I think there is genuine burnout. Also it makes sense that the more grizzled on HN have lived long enough to see the fruits of the labor, perhaps just tangentially, and what it has wrought. Coupled with the industry treating its workers pretty poorly right now and shattering all illusions, it makes sense this sentiment is rising.
Five years ago I got flagged on HN and heard back channel that I was getting passed over for stuff via some little whisper in the right ear because I've been calling this shit out since my come to Jesus moment around it nearly a decade ago.
Today? I don't feel like criticizing Thiel-adjacent authoritarian goons changes my net prospects all that much. It hurts me with 65 and helps with 45 (or something), instead of 95/5 like a few years ago.
I think the burnout is real: the consequences are too obvious and most people are reasonable deep down even if we all get carried away sometimes.
