All very fair points! To be clear, I'm not thinking WAUs just for the social use case. Could be for payments, marketplaces, audio streaming, or "other stuff."

Assuming new popular use cases do emerge, what sort of changes do we need for the infrastructure to be ready to handle that sort of volume? Is it mainly having pro/paid relays with clear and sustainable biz models?

I agree we need a mindset change, but I think the amount of new building happening under the surface is about to start bearing fruit. Let's see!
