When Steve Jobs and Steve Wozniak set about making the first Apple computer, there’s no way that they would have thought it would end up turning Apple into the worldwide juggernaut it is today. It’s an oft made statement that it was a lot easier in the 1970s to make an invention than it is today. In some ways this is true. Back then the world really was an investor’s oyster. There were some many things that hadn’t been tapped into yet, especially in the technology industry.
However, it would be inaccurate to say that there are no more invention ideas for you to take advantage of. Whilst there may appear to be fewer novel ideas, that doesn’t mean that you can’t take a pre-existing idea and turn it on its head to put a different spin on this. A key example of this would be the adaptation of the in internal combustion engine so that it would run on diesel instead of petroleum. Whilst the invention of the engine wasn’t new, the way in which it was powered certainly was. https://www.reddit.com/r/GreaTech/comments/8q1357/invention_ideas_and_technology/
