i like your logic .. but i think Go have more than just Google, it also had Rob Pike and Ken Thompson as designers

two legendary programmers

And yet somehow they managed to ignore the majority of what has been learned in the last several decades of language design progress.

Given their experience, I strongly suspect they made the choices they did knowingly, rather than out of ignorance.

These two comments are not mutually incompatible. There is also a reason I've been heard to say that Not Invented Here syndrome was invented at Bell Labs.
