- No, but I think some are overly fond of the continuum as a philosophical
- concept that seems to be naturally correct. It is a bit like the attachment
- to Euclidian geometry. L-S shows that there is a certain arbitrariness
- to this mathematical concept.

- No doubt replacing a model that one knows and loves with one that is new
- and foreign will be a nightmare for many physicists. It will only happen
- from necessity. I think the key to doing this will be tests of Bell's
- inequality. I have posted arguments and my paper is now under review that
- shows that quantum mechanics is an incomplete theory. QM does not predict
- the delays to be expected in tests of Bell's inequality. If these arguments
- hold, this will provide the incentive to do the experiments to measure these
- delays. QM needs to be extended to predict these delays and the only way
- to do this is through experiment. My expectation is that these experiments
- will provide the first measures of the structure of quantum collapse. I
- think it will be impossible to account for this structure with a continuous
- model.

- My approach is much simpler than this. The class of models I am proposing
- are elementary and simple. Going from these models to experimental predictions
- is the hard part.
