Robots
Here’s something you might not have known about robots. They were around during the steam-engine days in the 1800s. Yeah, we had AI back then, but they were powered by steam instead of electricity. And they moved freakishly fast for what you’d expect from an 1800s piece of tin.
Today, we have robots so highly advanced that we rely on them to take care of the elderly. We don’t know whether it’s science or magic, but somehow, robots are able to manage the most demanding tasks with very few technical issues. It’s probably just a few years before we get to see a full robot battle between two countries.
