Dillon PentzSomeone complained that the xkcd Dependency comic is unrealistic because it only shows one critical dependency you've never heard of.
However, it all makes sense once you realize it's actually a fractal:
enoch_exe_inc@dillon It’s dependencies all the way down, though even that is a bit of an oversimplification. I like to think of the infrastructure of the Internet not as haphazardly-placed building blocks, but as a literal web of trusses connecting nodes together. These trusses differ size and purpose, but they all use essentially same designs. So, if someone changes or obsoletes the design, the whole Internet comes apart.
