I would argue that common sense is actually quite common, but the application of it is not. And there's studies that suggest as much. In recent studies, researchers have found that despite people knowing the *right way*, or *better way*, they do it the wrong way (or less than ideal) way anyway. Which perfectly couches with my belief on free will - that people have much less free will than they think they do. What they lack in free will, they have plenty of self determinism, regardless of what information they have.
They replace zero jobs. Robots only exist because humans created them to do tasks for humanity. They don't have a purpose to exist without us. Every robotic thing we've ever invented since the dawn of existence has needed constant upgrades, constant maintenance, constant new materials, etc. Robots will always be deeply flawed because you can't create a perfect thing from a non-perfect source. Since humans create robots, robots will always be deeply flawed. They will always need firmware updates. They will always need repair and maintenance. And anytime they make a robot that can do a persons jobs - humans always come up with a new way to make money (Bitcoin, Uber and Lyft, Etsy, Fiverr, Youtube, Twitch, and on and on etc.) The only way robots replace people is if you remove all logic, logistics, and context from the conversation.
