Now I'd be the first to admit that Tierra is a wonderful program, but
I can't help getting the feeling that a logical point is being
overlooked here. Is it not the case that Tierra `creatures' can only
be considered `alive' because they have what we might think of as
`life-like' characteristics? And how do we define `life-like'? I
think we're still left with a sample size of one!
P.S. Are viruses alive or dead? Just a thought.
The absolute, eternal dogma (for the last decade or so) is "Life is
self-replicating information." Thus, it's the genetic information
inside you that is the part that is *really* alive. And viruses are
alive, although they're dormant most of the time. And the things in
Tierra are alive, as least as long as you keep Tierra running...
