Of course modeling the climate is a worthwhile activity but I'd willing to bet a whole bunch of money that over the next 50 years, the models will be improved upon significantly. I'd also guess that you'd be willing to admit this as well.

I've already admitted this. But at the same time certain aspects of the models such as the effects of greenhouse gases will not be improved upon significantly, if at all. Radiative forcing of greenhouse gases is well understood. The only areas that are left for meaningful improvement are the positive and a couple of negative feedbacks.
