There’s a bit of Amdahls law here: If I’m “10x engineer” but just 10% of the day, that means I’m really a 1.1x engineer. And it doesn’t matter (much) whether I’m a 50x or 100x engineer in that 10% the max speedup is limited by the “1x” part.

I agree that 10 engineers can’t do everything 10x. Even 10x engineers can only let 10% of the code 10x faster, it might have a deciding impact on the end result. if a software product is all written by 10x engineers, it might turn out to be 2x as fast as the one done by average engineers.

And in software optimization, speeding up a program 2x usually requires 10x more resources. This is why I think the 10x concept still makes sense here.
