I found an interesting subtlety to the message here. They had a Python wrapper around a C library, and effectively never updated the library. I wonder if this was due to engineering decisions, hiring/expertise of their staff (or future hires), or something else (risk? etc). I imagine it is easier these days to find Go devs than C devs who want to work at a company like this?
Also, for a sense of scale, this rewrite took about 4 years to complete from first concepts.
