That's a very interesting observation. You see it a lot in "tradesy" videos on YouTube, machinists* and welders and woodworkers and the like. The humor and self deprecation - far more apparent than in most other genres of American media - is really quite close to feeling British. As a transplanted Brit, it's pretty comforting stuff to watch.
*This Old Tony's channel is a particularly good illustration of this point, among many.
Inheritance Machining is like that - a lot of self deprecation.
And the weird thing is, these are the people who actually make thing.
I think the success (not necessarily financialy, but in the public eye) of the American tech elite can be partly attributed how much more relatable these peole were than the previous ones.
For someone who was used to seeing these corporate types with their perfectly tailored suits who spoke in press releases, I think it was a refreshing change to see Mark Zuckerberg give interviews in his college hoodie in his typically awkward fashion.
I think this created a perception in the eyes of the public that these guys are different, and tech has coasted on this goodwill for quite a while.
