I kind of hope you're right. Any "hyped" industry/sector is bound to eventually needing to get back to reality, and focus on things that actually work, rather than spraying and praying prototypes and over-hyping them.
The individuals and companies building real products that actually improve something will stick around, either as they are, or at least as ideas, and most of the interesting stuff tends to happen when the hype dies down, as the builders continue as they were, but all the rest of the riffraff disappears.
There will still be a community and the ideas won't magically disappear, just smaller and more focused, which to me sounds like a much needed improvement over the current state of things.
