Things will always trend to maximum efficiency. In most cases that means larger, economies of scale. The difference is that we now have choices and no longer have to stick around if someone does you wrong. I don’t know why people think relays will be like a giant thing to choose from - they’re more likely to trend toward thousands of niche communities/ interests

You talk as if decentralized communication is a new thing, the choice was always there with networks like freenet or i2p as old as 20 years and more.
Read a quote (same YC thread) every generation has to learn old things as new again.
Decentralized communication may be old, but it’s been forgotten and the tech is old. Perhaps we’re simply bringing back bellbottom jeans, except NOSTr is a better platform to do it. A more global and efficient platform that is able to scale globally.
