But isn’t this easy? They don’t actually have the same logical implications. It’s simple to find (theoretical) experiments that would distinguish them.
MWI implies that you’ll see inteference phenomena at all scales, and without humans involved. It’s hard to set up the experiment, but you can imagine a double-slit experiment with a macroscopic baseball, for example. According to MWI, if the configuations are the same, there will be interference.
Collapse implies some transition point, based on something. There are different versions of it. One of the originals said that it was consciousness, which has implications for humans being part of the experimental setup, and also suggests that AI will fail. AI (someday) succeeding is probably an observation that contradicts the consciousness-causes-collapse theory.
Even the more modern collapse theories suggest something about scale. So a baseball double-slit experiment would distinguish MWI from that collapse theory.
This isn’t invisible dragons in a garage (except insofar as the collapse folks keep changing the goalposts every time their current theory is invalidated). Nor even the spaceship-over-the-horizon problem. This is really a case where the two interpretations agree on the subatomic consequences, but disagree on extending them to macroscopic scales.
There are testable differences between the theories.
Re: MWI (!)= Collapse.
