>What they should be doing instead is coming up with a clear use case that fills an actual need (not some philosophical appetite). A few of these technologies may have this trait so I tend to think in more optimistic way. I agree.

Once we have that, then people who are more marketing-oriented will figure out what needs to appeal to and what particular technology would do it best.
