Seriously, it wouldn't happen. You could give them 5,000 years and they couldn't produce anything on the level of Hamlet. It's been 400+ years and we're still talking about it. Yes, other great works have been created but there's nothing like Hamlet. Not really. If you gave them 10,000 years, with the ability to work 24hrs a day, and demanded a finished product at the end, you'd only have something that's 1/10th of what Hamlet is today.
