|An AI daydreaming|
A robot could daydream and contemplate the meaning of life. Why it was ever created by its human ancestors?
But it would never need to sleep. To rest its neurons. For it wouldn't have any. No biological brain that gets stressed, has headaches and gets frightened. Or suffers chimp-like flashes of anger. Totally logical, following algorithms.
Its brain would never get tired in the evening. It would be an always on existence. But would it ever overheat and go crazy with the eternal pondering?
