I agree that if the trend towards decentralization and privacy continues, then everyone benefits. My concern would be the new technology adoption outpacing the adoption of privacy-focused and/or decentralized technologies or protocols.
If the majority of people adopt a new device or technology that is more revolutionary than a phone without adoption the corresponding decentralization and privacy protocols like we see here on Nostr, that could be a danger. And it seems inevitable to me that big corporations or governments will try to sell the next revolutionary thing in a way that forces you to buy into their ecosystem, just like Apple has done with their i-devices.
