> But there’s also a part of me that’s just like, how can you not be curious? How can you write Python for 5 years of your life and never look at a bit of source code and try to understand how it works, why it was designed a certain way, and why a particular file in the repo is there? How can you fit a dozen regressions and not try to understand where those coefficients come from and the linear algebra behind it? I dunno, man.

Because there's a lot of things out there which are also interesting, and you don't have time to do all of them, so you choose. And different people choose differently.
