+1 on the opposite problem being much, much more common. Especially in any domain or application where there is some deep science or subject matter expertise involved.
I've seen countless VC-funded startups which promise to combine "shiny technology X" with "problem Y" to create "amazing product Z". A lot of times, I know for a fact that "technology X" has never even been shown to make a difference on "problem Y". As in, I can point to literature of some sort that shows how it has a marginal effect at best, or is prohibitively expensive relative to existing state of the art. That doesn't necessarily mean "product Z" is a bad idea... but _so_ many ego-driven startup founders get fixated on selling the technology story instead of the product story.
Maybe the current macro-economic climate will wipe a lot of these guys out, since they'll be forced to figure out how to execute on the product side instead of selling the same ol' obvious BS tech/science story.
