Maintainers make the world go round, innovators MAKE the world.
As the frontier of knowledge expands, increasingly more low-hanging fruit appears on the horizon.
And then this somebody would be an innovator.
Innovation is inevitable; so too are people claiming credit for it.
Honestly, we need a better label for "anti-innovator" (conservative is taken)—they have an oversized personal impact on the world.
Either way those that would have to fill the spots would likely not be as competent in the doing.
