Consider the airplane.
Yes, the steam powered airplane is a dead-end branch in the development of the airplane. Unlike most of the dead-end branches, it actually worked, in a limited technical sense. Most research and technological development fail, and most of those which succeed in a technical sense end up being worse in a practical sense than other alternatives. There are a lot of gadgets where "the creators and innovators are told they…
I agree. So what? If you have a better way, you will no doubt be very, very successful and your name will be in history books.
