Why I sometimes like to write my own number crunching code

Lest you think mine was a shallow, knee-jerk analysis, this is my area of subject matter expertise. I get all the nuances, but I just felt like defending library authors, whom he unjustly threw under the bus, because that stuff is really hard. Like really hard.

Also, if you are using libraries written by grad students, then you probably need to find better libraries. All of the major battle-hardened ones like BLAS, LAPACK, CUDNN, TF, FFTW, etc., have had major big brains looking at them for years. Decades in some cases.

I didn't read it that way. I took the audience to be more junior programmers to whom numeric library code can seem inscrutable and terrifying. In my experience "write it yourself first" is very liberating advice that every programmer should take to heart. I would also cut the author a little slack since he is a library author and the post is a kind of ad for his own numeric library. It could have been worded better though.
