Hm... i agree with appreciate beauty. As for reproduce, in a microcasm they can: i.e. computer viruses. It is only via information, but it is reproduction. The key one I found was Growth.
If science were advanced enough, they could be programmed with emotion. Given an electronic coding as it were, that makes them think they feel something. Thus they would feel in a fashion that is disturbingly similar to our own manner of biochemical reaction.
As far as thinking, that is an only for now type statement. As we creep up on true AI, I shudder to think about the Computers Rights movement that will doubtlessly spring up. And would it really be silly, if the computers actually came toself awareness?
They can do, in a fashion, most things that we can do, or will likely be able to do so. They even eat/excrete. Think about the fuel/exhaust system in a car for that one.
It seems to me they mainly simply cannot grow. Hell, on some assembly lines you even have machines building their own type of machine.

I do not believe these to be unanswerable, nor even stumpers. Just thought provokers. Thanks for your time, dan.
