Yes, I watched the video. Inventing stuff is obviously very expensive and I doubt anyone could have done it without being financed in some way.

Why are you so sure that the eventually hypothetical inventor wouldn't have patented it? Inventing is expensive and one would presumably want to make the millions spent on the project back and isn't your time worth anything?

I am happy that the invention wasn't delayed considering how much it has changed the world.
