eli5 Why weren’t machine guns possible to make in the past?

What stopped 18-19th century armies with guns from being able to create automatic weapons like AK-47s and Uzis?
Since they don’t use electricity I feel like they’re made with materials and technology that was already available in the 1750s, surely they could’ve put their heads together to create a machine gun and just annihilate any ops…

Thanks

they did, full auto was the goal, it took years to as you said “put their heads together” research takes time, some one smarter (more imaginative) then every one else, luck, money. things don’t just appear over night

do you even know how much engineering and moving parts go in to a semi or full auto gun?
