This actually reminds me of a book by Charles Stross called Accelerando. Human explorers during a time in which people upload their minds to computer systems travel to (and this part is fuzzy in my memory), a world orbiting a brown dwarf. The world is just a giant computer and it’s inhabited almost entirely by superintelligent banking scams and viruses. It turns out that almost all “life” in the universe is like this, just parasitic AI that serves no real purpose other than to fuck over other people for short-term gains. Anyway, I’ve been thinking about that book more and more in recent years.
