Wait, it was way less than 10 years.
I'm talking about Google Realtime. Or reader? Or buzz?

You get the idea. What's revolutionary today sometimes becomes the substrate for future innovation. Sometimes it gets cast by the wayside, even in the face of significant "user" (developer) popularity.
That's not proof of negativity; just realism. Negativity would be "no new innovation will ever get traction". Optimism would be "all new technologies will change the world" (c.f. https://www.npmjs.com/browse/depended). This is neither.
It's not proof of negativity in the tech community. If anything, it's a proof that tech community often can't pause and look if a particular idea makes engineering sense.
That's how we ended up with Electron.
Google actually delivers a real world product incorporating the most advanced AI we've had the chance to experience, and half the HackerNews comments are "Wow, this is so dumb, can't wait for it to become technical debt in 10 years".
