I wouldn't say the uncertainty principle has been proven incorrect.
As far as I know it still applies to things like position and momentum.
You're correct that a long time ago it was also thought to apply to waves versus particles, but this paper talks about some experiments in the last decades of twentieth century, and ways we need to re-think the exclusivity (or lack thereof) of wave versus particle observations:
Updating the wave-particle duality
I think it's translated and lost something in the translation but hopefully you can get the general idea if you wish to read that.
The wave-particle-duality, the fundamental component of the new quantum formalism in Bohr’s opinion, must be reformulated by incorporating the results of some experiments accomplished in the last decades of twentieth century....
Today, it is clear that intermediate particle-wave behaviours exist and, in addition to that, there are single experiments in which both classical wave-like and particle-like behaviours are showed total and simultaneously on an individual system.

Does this lend more credibility to the John Titor story??
I can barely handle news about my universe, let alone a multiverse.

Depending on whether they will be observed or not.
That is what makes the difference.
It was proved beyond doubt in the double slit experiment.
The presence or lack of an observer decides particle or wave form.
An observer can be a person or detector doesn't matter.
Yes I'm well aware of how it works. I'm glad you mentioned the fact that it's not just conscious observers which can collapse the wave function. Any detector placed at the slits will cause the photon to act as a point-like particle even if the results of the detector are never observed by a human being. That is just the result of entanglement and decoherence imo.
