> [...] you get a degree of viciousness, competitiveness, and steel-eyed execution

I think there's a lot of truth to that. (Aside: Many manage without the viciousness part. It's not their fault their parents lined them up with an internship and a research paper co-author in high school, and they're not jerks about it.)

Though the current generation of students didn't invent hyper-competitive. Before software engineering jobs (and startups) were high-income and high-status, you'd see that mentality among many people on track for Wall Street, for example.

Another example: Before CS was a go-to for the hyper-competitive, a mentor of mine actually switched from pre-med to CS, at an Ivy, because a percentage of pre-med students were outright sabotaging other students, and it turned him off of the field.

> that a lot of older Americans just aren't used to.

Though, there have been -- and hopefully will remain to be -- people doing it for the love of the field, who are not impressed.

Other than the genuine people being crowded out of admissions slots and fratbro interviews by Wall Street types...

If a Palo Alto helicopter-parented overachiever McDojo black belt tries to pick a fight... with a humble rope-belted person in Asia, who's studied martial arts for the love of it... the latter will chuckle good-naturedly, and help the Californian up off the ground.
