Newcomen engines are mere curiosities today, because we have better sources of power (better engines). In the past, they had better sources of power too (donkeys, wind, water, or human slaves). Newcomen engines, like all technologies, are only viable in certain economic environments. In all others they are curiosities.
Steam engines were known since the first century, at the vert least: https://en.wikipedia.org/wiki/Aeolipile
It does take a lot of imagination and creativity to come up with new and better ways to use an already existing idea. We're currently just scratching the surface of what LLMs are going to do for us
