An inspiring, albeit daunting, write-up for someone like me, who has been a python coder for over 10 years, but who has never professionally coded in C or C++. I'd be pleasantly surprised with myself if I could one day debug like that.

Also somewhat depressing that, yet again, the GIL was to blame, and that after all that impressive investigatory work, the fix was (spoiler alert!) "rewrite the offending function in C".

I predominantly develop in Python but somewhat frequently peer into the C++ and CUDA underlying Pytorch. I am not a competent C or C++ programmer but often am able to debug and fix bugs that originate in the lower levels of the stack. That ability developed just through exposure and focused prodding when I found issues, but I don't think it has much relation or translates to being a professional coder in C/C++/CUDA. Coding and debugging are different skill sets IMO.
