Google python binaries are more akin to docker or even vm images, even if the actual technology used predates docker and even linux VMs. They contain something like a slimmed-down linux distribution, not just a binary. EXTREME predictability (e.g. as never ever using the system's libssl), in trade for huge binaries. They go pretty damn far in this: you won't catch a Google binary even using most of libc.
