If there were to be a sudden explosion in human space exploration, would you suddenly be able to invent more things?

I have heard it said that it is hard to invent things now days, because it has all been invented already.

While I don’t think this statement is fully true, I do think there is some level of truth in it, based on the fact that we make things we need, and what we need depends on our environment.

If human space exploration and travel were to suddenly become the norm, and we all had access to that environment, would it be easier to invent things again?

Do you have any idea as to what kind of thing you may invent?

(This question is inspired by a space exploration documentary, that showcased a zeroG sex harness, for astronauts to be able to reproduce in space without bouncing off the walls.)
