> Consciousness causing the wave-function to collapse isn't a very popular idea these days and there are alternative explanations, though as far as I know there isn't any evidence that it is involved or if it isn't. The wave function collapse happens regardless of whether a human or any conscious being is present, all that is needed is something does an observation. Imagine a scenario where a QM experiment is done, and the result is recorded by machines and stored as a data file. Let 100 years pass then distribute copies of the file to a million people. They will all see the same thing.
