Ancient Greeks were 1000 years ahead of their time. The more you study about their history, the more you go crazy. For example the first vending machine or the automatic doors, or machines that working using steam. They were talking about robots (Talos) and had a God of Technology (Hephaestus). Some scientists believe that if Greeks didn't invaded by Persians or Romans and continued to give all this knowledge and technology to the world, we would have the industrial revolution 1000-1500 years earlier.
