Earlier quoted context omitted.
>> The optimal solution is for management to not let high-productivity talent from leaving - increase their comp to whatever offers they might get in the open market. >> Investment bank and management consulting figured this out a long time ago. That only works if your business makes piles of money, like investment banks. Or FAANG. The rest of us have a % of money to spend on talent.
The rest of you waste more money hiring 5-10x more mediocre engineers to try to mitigate the bus factor or whatever. And it's still not as good a product as it will be built by a handful of good, over paid and over worked engineers who really know what they're doing.
The idea that there is a single solution is absurd.
