This right here, it's just crazy. On one project we invested in a private cache of prebuilt/binary pip wheels, as much as it complicated the build and maintenance, it saved us so much time and effort in the long run, and was ultimately a productivity boost.

I really like it that the x86 monoculture is being disrupted, and enjoy the benefits of low-wattage high-performance systems, but we still have a long way to go.
