I would not agree on that point. It really depends on company's structure. I mean it also depends with people that makes the team. I would say there are a lot of unknowns but I would certainly not generalize.

How I find your argument is that one distinguished engineer from US could do the same with the use of AI.

I worked with both and I know great and bad engineers from both sides. Only thing is that US has a bigger pool of great engineers.
