there isn't a big structural difference between the tech and entertainment industries vs., say, healthcare or construction. they're both IP-driven and largely virtual, with lots of winner-take-all dynamics and potential economies of scale and scope.

most ventures fail, whether it's in tech or entertainment. tech has billion dollar flameouts too--webvan, theranos, etc. entertainment has startups that hit big too--parasite for example. founders who exit successfully can more easily raise the next time around, just like directors and producers who have a hit.

each industry thinks it's unique and different, but that's due mainly to ego, not to (many) true differences. even cultures largely overlap. people with gobs of money can (and if warranted, should) fail too.
