Of non-obvious inventions. My argument being all inventions are obvious once attention is applied to that area and scope.
Everything requires attention to be seen, once somethign becomes "obvious" is fully determined where you're looking and the scope you're zoomed in on.
E.g. "matter is solid" until you zoom in and realize matter is mostly made up of space.
And bringing things more expediently is the actual opinion here, unsupported, where arguably it actually slows down not only progress but the value of that progress not being as widely distributed as it otherwise would be.
