Q: Follow-up question if you have thought about it do you also imagine them using it for mostly silly pointless things like we humans do?
A: well let's unpack the implicit thesis you just snuck into the question, which is that you think the internet is mostly silly and pointless. i disagree with that part, and then about the aliens i'd say their internet wouldn't be pointless either. ask them why they made it. if you don't understand their reason, then that might be just a language barrier
