It's more of a brain teaser than a theory. It's certainly not a statement of fact.

There is a significant portion of the quantum community that want time travel to be viable. They interpret observations with that subliminal bias. It's too much trouble and headache for established scientists to argue, which leaves it up to us mavericks to say the emperor has no clothes. We're used to taking scorn & ridicule because having an alternative opinion, no matter how logical, is not something America's intellectual environment tolerates; just ask the scientists who disagree with the climate narrative.

OK, I want to hear from you computer men about this thought experiment / paradox, especially in the context of the IRL potential of quantum computing as described:

New Quantum Paradox Clarifies Where Our Views of Reality Go Wrong

Nonetheless, Gisin is not averse to thinking that maybe, one day, the experiment could be done using complex quantum computers as the agents inside the labs (acting as Alice’s friend and Bob’s friend). In principle, the time evolution of a quantum computer can be reversed. One possibility is that such an experiment will replicate the predictions of standard quantum mechanics even as quantum computers get more and more complex. But it may not. “Another alternative is that at some point while we develop these quantum computers, we hit the boundary of the superposition principle and [find] that actually quantum mechanics is not universal,” Gisin said.

Leifer, for his part, is holding out for something new. “I think the correct interpretation of quantum mechanics is none of the above,” he said.
