A Node.js Proof of Concept Virus

So, I have these random trains of thoughts sometimes. They go like this: I wonder about the universe, about evolution and life out there, wonder if someone else is looking back while I'm staring up into the night sky. Is there intelligent life out there? Is life merely an inevitable consequence of the laws of thermodynamics, serving the ever increasing entropy? What about artificial evolution? Did no-one ever continue Thomas Ray’s mind-blowing work he started with Tierra. What’s the state of digital evolution and life in a computer? Is self-reproduction enough? Are computer viruses in this weird state of being not really alive but not really dead either as biological viruses are? Are people still writing those viruses anyways? I am learning so much about Node.js right now, but I never heard about a virus infecting Node.js apps.
