This is Hacker News, ostensibly created as a website for hackers and founders.
If you are a hacker and a founder then a ton of this advice is spot on.
For example it's a simple concept but he absolutely nails a key factor by distinguishing between A, B and C employees. A high performing team really can't have more than one or two C's. It moves them out even if they're nice, cool, good people. If the team is run by good humans it does what Mr. Beast does and gives them severance.
I can smell a couple C employees fuming on here and in the Twitter thread. I've had C employees work for me and they were always the ones who lobbied me hardest for being more tolerant of mediocrity. Sorry but you just have to hold the line against the average if you want to succeed, this is dictionary definition level of obvious. To be above average, you have to be above freaking average. Half the world is C's and to win your team needs to not be in that half.
I argue that in many cases owners and managers, those who are posed to benefit from this ideology, are the ones which poison the mindset by punishing proactivity and being arrogant. There's also D employees, those that are unable to create value by the conditions set forth, they recognize the pointleness of their job and actively do the minimum and create excuses just to not get fired.
