There are computer based systems that evolve. The environment is simulated to direct the desired evolutionary direction, the thing is simulated and reproduces and mutates by rule

For example antennas might live in a simulation where the EM waves of the right frequency are feed, with the most nourished antennae breeding to make many children and less nourished antennae having few children; over many generations an excellent high gain antenna with whatever other features were adaptive (size, shape, ...)

I wouldn't call those alive though we use many life associated words to describe them.

I personally would put the life line above viruses, Wikipedia needs to differentiate between viruses and cellular life.

I feel like we will have computer viruses that mutate and evolve and those that can better spread, better avoid detection will thrive while those that cannot will be destroyed. When that happens will we call it life?
