It really depends a lot on how junior those “talented” employees are.

The senior types won’t let themselves burn out and self-destruct, it’s only the gifted juniors (who are way less productive than the seniors and lack the senior’s capability to enhance other people’s productivity, no matter how amazing their raw talent is) who will fall for that shit.

Put gifted juniors through the meat grinder a couple of times and the ones who are left recognize that shit a mile away and either avoid ending up in such work environments, refuse to take that shit and exercise informal control around them to stop it if they can or simply leave.

It’s not by chance that the Tech companies with the worst work environments (such as Google) are heavilly focused on straight-out-of-uni graduates with high grades as “talent” - their meat-grinder environment can’t retain people beyond a certain seniority unless they’re moved out of the meat-grinder parts - and this then gets reflected on the quality of what they produced (“messy” barelly begins to describe how badly designed and architectured the software that comes out of Google is).
