Any sufficiently large amount of information exchange could be interpreted as computational if you see it as separated parts. It doesn't mean that it is intrinsically computational.

Seeing human interactions as computer-like is a side effect of our most recent shiny toy. In the last century, people saw everything as gears and pulleys. All of these perspectives are essentially the same reductionist thinking, recycled over and over again.

We've seen men promising that they would build a gear-man, resurrect the dead with electricity, and all sorts of (now) crazy talk. People believed it for some time.
