Gemini devs could have contributed to something else? Sure. They didn't, though.
Historians avoid counterfactual arguments because they lead nowhere. Perhaps the timeline without Gemini is worse. Perhaps it's better. Not possible to say. Best to just live in the moment.

Not the argument I'm making. I'm observing that others' energy that gets captured (or more accurately, spent; i.e., fails to be captured for use elsewhere) as a consequence of Gemini's gravity is wasted. It's necessary to make a distinction between Gemini's originators and people sucked into its orbit.
