I mean, besides the empty platitude that we have no reason to assume applies here, we can easily search and find Tao commenting on the history and philosophy of mathematics.
This is a really weird subthread.
Clearly Tao knows the former, but apriori that does not imply he knows the latter.
Not saying he doesn't, just saying one does not imply the other.
Even if you go back and read the original papers, you'll miss all that which happened beyond the page.
If Tao has a knowledge of the topic (which he does), then it isn't by virtue of being a mathematician per se, but by virtue of an interest in the history of mathematics (which he has). Knowledge of math is enormously helpful here, but it does not imply historical knowledge.
