We often designed various protocols and other stuff in IT as per 'lets come up with some simple chat to validate things and go ahead', or principle of least complexity (apart from classics like IBM and Microsoft but they were done specifically to make vendor lock in as big as acceptable). Its also ie in telco protocols - designed around trivial Hello handshakes, I can explain protocols like that to a child and it would grok it. Not great for advanced security but thats another topic. Or SSL handshake which is way more modern.

Math just represents this reality on most abstract level, it doesn't care if complexity for some human brains is trivial or almost fractal-like.
