I agree, but then again, the market accounts for all those "multi-dimensional factors". Maybe what should be added is that there are external and interal factors that decide of which language is better. External factors have been already discussed. Internal ones are those that correspond to the company internal structure, culture, etc. For instance: If you have a team of people writing Java you wouldn't choose Python at all.
