Also "decentralized" can be associated with web3. I mean I'm all in for a decentralized web without crypto BS though this is vague as well.
Since we're at the decentralization, how will the conflicts be solved? What if a corpo with resources would create more nodes than already exist - we end up in regular web ruled by organizations and private entities...

You’re definitely not writing nonsense — it’s an important point.

Betanet’s goal is indeed to replace the public Internet as we know it, but it does so by building a fully decentralized overlay network on top of existing IP networks (fiber, 5G, satellite, etc.). So it’s not physically replacing cables or routers but rather creating a new logical network stack that sits above those physical layers.

The first paragraph could absolutely be clearer about that distinction — I agree it can be confusing at first glance! Something like:

“Betanet is a fully decentralized, censorship-resistant overlay network designed to replace the public Internet’s logical transport and routing layers, while using existing IP-based physical media.”

I think clarifying that Betanet is a network overlay rather than a physical infrastructure replacement would help new readers get a better intuitive grasp early on.

You can't replace "the public Internet as we know it" without also replacing the physical cables that Govts. and corporations control, that span across the globe. You're replacing the World Wide Web, certainly not the Internet, and even that's a stretch.

If we go back to what K0 said in the original video announcing Betanet, regarding the mutually assured destruction part of Betanet, then it seems like Betanet is effectively DOA, because in order to thwart Betanet you would need to compromise the security and privacy of normal Internet traffic... which Govts. and corporations are already doing, Betanet or not.

Agreed. It will be adjusted.
