@Mammmood - I remember watching a TV show that talked about the question of what is a computer, and tried to answer the question, when was the first computer built?
Immediately I thought they were going to talk about Apple or Microsoft or IBM or something like that. To my surprise, they talked about this ancient analog computer, made up of gears and moving parts, which was supposed to simulate the motions of the planets around the sun.
I guess it depends on what you want to define as a computer; this thing had limited application to astronomy, but the TV host said that it had the sophistication of a Swiss watch, using the parts they had back then.
I think it’s remarkable to realize that mankind hasn’t changed that much. It’s just a matter of what resources we’ve had access to.
