Once we get to the point of AIs approaching sapience and/or aliens surfing our internet, we can change it to people.txt.

Toaster jokes aside, I doubt AIs will identify more with primitive search engines than other sapients.

I'm sure that's true, but I don't see why it would be unreasonable to use more inclusive language from the beginning.

Reasonable and pursuable - on a site you run, you could make humans.txt redirect to people.txt.
