Sigh. As well as being a good read, Michael Crichton's Jurassic Park has a message. It is: Don't do this. Even if you can, don't do this.
God knows what kind of monsters they'll accidentally create. The truly scary ones are probably microscopic and could spread like wildfire killings millions before a means to combat it is figured out. I mean, maybe we'll find out why the Neanderthals went extinct, and maybe we won't like the answer.
Or not.
When will our culture ever get over the 1950's scifi B-movie paranoia?
