The various interpretations have all been about trying to make sense of the non-intuitive/non-common sense results of experiments.

Even things like "particle-wave duality" are a way of trying to get a handle on observations.
Those things we call particles that seem to act like waves are really neither particles nor waves - they are whatever they are and we're trying to figure out what that is.

Skepticism is not a position; it is an approach to claims.

Right, because sub-atomic particles keep looking over their shoulders. No

This happens due to interaction, and anyone I've spoken to would deprecate usage of 'observation' as a poor term.

A physicist, trying to bring the cookies down to a shelf I could reach, explained it to me this way "We can't simultaneously know position and momentum. So what. All that's saying is I can ski and I can swim but not at the same time." That I can get.

There is only one really serious philosophical question, and that is suicide. -Camus

And we even have evidence to support that. Yes
