gollark: Sorry, network issues, back now.
gollark: I mean, we're different in... quite a lot of ways, if similar in others.
gollark: Well, I thought about grass, but then I got bored of it.
gollark: Well that just makes it meaningless.
gollark: It's not even really the same thing as "intelligence", which is "ability to solve problems", roughly.
