So if Americans are not skill enough and you lose profits training them to be productive, but you hire even less qualified than that, how do you not have the same if not greater loss getting them productive. This is BS Elon and you know it. JP Morgan estimated that even skilled workers need at least 3 month's to train a qualified person to do the same job as the previous employer. So this is know throughout all industries. No one can walk into a a few million lines of code and be productive to the level of ownership of the codebase anyways and you should know that.
The total number of verses in the Bible: 31,102
Not a million lines of code with call stack traces but plain text. Yet it takes scholars lifetimes to understand the meaning and they never truly do. But you want that immediately out of US workers on code bases but make exceptions for less experienced people. Clown 101.
