A pattern that appears in history is that the inventors of the invention notice something peculiar and instead of just shrugging it off they investigate it and learn what makes it do something. this is called the eureka moment. They use that in an invention or someone else uses it in an invention but could only do that because the first person wrote it down. Another pattern that can be noticed in history is that when a labor-saving device is slowed down by mobs of people who have the job the device is supposed to help will try to destroy it so that they make more money instead of everyone having more money and time. Nowadays you don’t see farmers trying to destroy tractors but if they did then the ones who use it will make more money and have more time to do other productive things and the ones who don’t use it make less money and less time to do other productive things
