Though we observe the effects of the double slit experiment on the wall with the interference pattern. Thereby not collapsing the system and taking a screenshot of the un-collapsed system? I would argue the wall is an unconscious camera in my example. Because when observed during the experiment, the interference pattern disappears. But not if it's observed after. Secondly, the more and more I re-read the parent comment. The less and less sense it makes. >No conscious mind will ever be able to observe anything about a quantum system that has never been observed by a conscious mind. That isn't really true in concept though, as in my example, we observed a quantum system at play that wasn't observed during its' "execution" so to speak. We literally wouldn't be discussing quantum experiments and quantum experimental phenomena if his statement was "completely" true.
