While I agree with everything you've said, I also see that steady, incremental progress is being made, and that as we identify problems, we're able to fix it. I also see lots of money being thrown at this and enough people finding genuine niche uses for this that I see it continuing on. Wikipedia was trash at first, as were so many other technologies. But there was usually a way to slowly improve it over time, early adopters to keep the cash flowing, identifiable problems with conventional solutions, etc.
