No, I don't think that's happened yet. I still know tons of people excited to build for "web3".

I don't think we need "rich" websites with javascript, "smart" phones in everyone's pocket, or "social media" at all.

But those all happened, and it seems to be a lot of the same vibe for "web3" builders right now.
