I'm not sure what you are trying to say. Are you talking about a segue or a segway? A leaver is much more useful than a Segway but they are both completely different things.
Why are you comparing a machine to a leaver? Also, the Segway as a product wasn't nearly as popular as the inventor hoped. Are you saying people who think AI will flop like the Segway did are wrong or are you saying that the Segway is some super tool and AI is not?
