If you could live as your fursona in an anthro version of our world, but it had to be sometime in the past, what year or era would you pick?

Technically, one second ago is in the past...

Though on more serious note, probably sometime after the development of nuclear energy at least, because my sona is robotic in nature and fission-powered, and while he technically has tech advanced enough to extract and refine the needed fuel himself, it'd be less work if some already existed to trade for or something.
