Okay, I think we've reached a point of reflective disagreement.

I agree with you that Kelly was wrong to be enamored of his formalization's output on the timed particles example; it's either a regrettable flaw that must be lived with, or a regrettable flaw that we should try to fix, and I don't understand enough of the topological math to tell which.

However, the unjustified Occam prior in the standard Bayesian account of science is also a regrettable flaw - and Kelly has demonstrated that it's probably fixable. I find that very intriguing, and am willing to put some time into understanding Kelly's approach - even if it dissolves something that I previously cherished (such as MDL-based Occam priors).

Reasonable people can reasonably disagree regarding which research avenues are likely to be valuable.
