Many-worlds needs another 50 Years

Sean M. Carroll posted his monthly AMA podcast, and he pushes many-worlds as usual:

3:09:38 jonathan Goodson says "I heard you opine that within 50 years many worlds will emerge as the dominant interpretation of 3:09:44 quantum mechanics yet over the past 50 years the number of different interpretations has increased significantly and no major contender has 3:09:51 yet been ruled out." As NDavid Murman remarked "New interpretations appear every year none ever disappear." What 3:09:57 would need to occur for many worlds to buck that trend and emerge as the clear winner and why did you predict the resolution will occur in this century

3:10:05 you know I might be wrong in my prediction but that is my prediction and I think that these processes are gradual i don't think that there's any threshold 3:10:12 you cross and suddenly everyone says oh yes it must be many worlds. i think that 3:10:17 what will happen is there is now here in 2025 a lot more attention being paid to 3:10:23 quantum foundations than there was 50 years ago. so that will lead to more progress and the way the progress will 3:10:30 happen is people will think deeply about the different models and their implications and they will both look for 3:10:36 experimental tests of them and they will ask how those models fit in with other things we think are true in physics 3:10:43 whether it's quantum gravity or particle physics or atomic physics or whatever and certain things will fit better and 3:10:49 better certain things will fit worse and worse and I I do believe that the progress will be made you know maybe 3:10:55 it's wrong that it'll be 50 years maybe it'll be 200 years i don't know for sure 3:11:00 but at the rate at which I see progress being made I'm optimistic that it'll be 50 years.

No, there has been no progress in quantum foundations for about 90 years. Our best theory is more or less the same as Von Neumann's 1927 Trilogy on the Foundations of Quantum Mechanics.

A common complaint is that von Neumann's theorem against hidden variables had a locality assumption, and did not rule out spooky theories like Bohm's. That's right, but those theories are considered unphysical by most.

Many-worlds started in 1957 with Everett's thesis. That was 68 years ago, and it still makes no sense.
