That's a pretty human-centric view of the universe. The thing about aliens is, they're alien. Maybe they regulate self replication, therefore the humans need to be licensed. Maybe they can't handle the concept of not being alone, like Kricket. No way to know up front.

I'd like to say we have things, therefore humans are slightly more likely to build stuff than destroy stuff. I'd hope civilization works that way everywhere, but there is no proof of that. Really, there isn't all that much evidence.

We'd share physics and math, and that's about it.

However, this particular article is nonsense.
