As a lifetime experimenter myself, I'm going to play the cards I'm dealt and I sure like slack in the system, but mainly to make up for my other weaknesses :)

One person's idea can be good enough to be the most revolutionary thing in a field, but it still may not be as well thought-out as if more than one worked on it together from the beginning.

One person's physical efforts can almost always be dwarfed by a team of some kind, and that might be the only way for an idea to become reality, but it's not going to help if there's not a proper team to join or resources to build staff from scratch.

Since most teams do not contain an absolute genius, at least they come up with products because they have a team. Excellent products sometimes, but not often genius level.

In some fields they really think brains are the most important thing, but it's too rare and everybody knows it.

So if they want to get to market any time soon they have to settle for what they have to work with until such a rare genius comes along.

Which may be never so no time to wait, but by the time some miracle-working wizard shows up it's too late because the team has no drop-in task for them to perform, and has not naturally been formed with the necessary structure to leverage anybody's wizardry by then. So never mind, they can't recognize it anyway.
