Generations before us made huge advancements as well. The industrial revolution for example. Manufacturing in factories has changed how the entire world operates. Or for Egyptians, I’m sure they used intricate pulley systems to move large bricks for building those pyramids. We speculate of the future, just like I’m sure previous generations would have…I think of colonizing other planets, moons, etc…whereas they might have thought about flying machines, and new and better weapons for war. I think it’s instinctive to think about the future, whether it’s accurate or not.
