in tech at least even if you fail, you are developing valuable skills that can be used elsewhere. Plenty of failed startup founders end up at other places in engineering or management roles
not creating a billion dollar startup isn't a failure, tons of people in the tech industry retire as multimillionaires essentially working a 9-5. A lot of people on HN seem to think if you don't make the Forbes list you are a failure
I'm not really sure that their statement is temporal or regional. With failure in general comes lessons that can be applied to other situations, regardless of anything else.
This assumes we can come back from the failure without major consequences, and we'll still be in a position to leverage the learnings from that failure. I think the OP is pointing to one of those scenarios where that's less likely.
