That's a fair point, but somehow the nervous feeling isn't limited to sharing CPU time with strangers! The amount of platform complexity abstracted by the GCP

That's a fair point, but somehow the nervous feeling isn't limited to sharing CPU time with strangers! The amount of platform complexity abstracted by the GCP services is staggering. This is the job of taking a (hopefully) understandable piece of computer code that represents some real-world logic and installing it into reality, in a sense. It's clear that it's a very messy world out there for a program.
