Actually they used to (polymorphic viruses), but do no longer.
The hypervariability was quite useful to evade pattern-matcher
artificial immune systems.
But the actual reasons computer code doesn't mutate it's because
it's brittle. It's lacking criticial features of fitness of darwinian
systems, namely long-distance neutral-fitness filaments and maximum
diversity in a small ball of genome space.
Biology spend some quality evolution time learning to evolve, human
systems never had the chance. But it's not magic, so at some point
we will design robustly evolving systems.

It's rather straightforward to do. You need to spend a lot of time on
coding/substrate co-evolution, which would currently require a very large
amount of computation time. I doubt we have enough hardware online right
now to make it happen. Sometime in the next coming decades we will, though.

Where is the power plant of a green plant, or of a bug? It's a nanowidget
called a chloroplast or mitochondrion. You don't take control of it, because
you already control it.

Cooperation and competition is a continuum. Many symbiontes started out
as pathogens, and many current symbiontes will turn pathogens when
given half a chance, and some symbiontes will turn to pathogens (I can't
think of an example right now, though).

Sometimes, they do. It's called cancer. And if you've ever seen what your
gut flora does, when it realizes the host might expire soon...

There's apparently an infectious form of cancer in organisms with low
immune variability (some marsupials, and apparently there are hints for

Cooperation is just great, assuming you have a high probability to encounter
the party in the next interaction round, and can tell which is which.
In practice, for higher forms of cooperation you need a lot of infoprocessing

In principle subsystems can go AWOL and produce a runaway autoamplification.
