I also think OP fails to understand how much more competitive tech culture is now.
Visit and talk with undergrads at a top CS program like Stanford, Cal, UIUC, MIT, etc. The culture is different because this is a much more competitive generation. When the acceptance rate into a top CS program is in the 1-5% range and laurels like being a Valedictorian, NHS member, JV or Varsity team member in HS, and taking 6-7 APs are viewed as table stakes, you get a degree of viciousness, competitiveness, and steel-eyed execution that older Americans just aren't used to.
Honestly, I like it. It reminds me of the culture and mindset I'd find amongst my Chinese peers in the 2000s and 2010s when they built China.
