I've been having this discussion with some friends.
Computers can generate 'random' numbers, but as far as I know, that isn't exactly possible. Maybe the current time is used and ran through some algorithms, but once you know those calculations, you can 'predict' which 'random' number will be generated.
Also makes me wonder if 'random' actually exists in the universe.
If I call out a random number, is it rly random?
If you flip a coin, the way you throw it, the air pressure, the surface, the friction, etc. all have an influence on the outcome - so it isn't rly random, right?
