I agree about private equity: it's merely the latest incarnation of rent-seeking or enclosure-building. The playbook is the same: cut costs, jack up prices, load up with exploding debt, go public or resell before the debt explodes. There is absolutely no value being created here. We saw the same thing with the corporate raiders of the 1980s (who bought companies below book value and scrapped them for parts).
But I do not agree that Web 3.0 will rise from the ashes. IMHO that's pure hopium. And you hear the same thing whenever people talk about federation.
Web 3.0 (and federation) offers nothing users actually care about. It complicates everything and makes everything more expensive. Centalized services won for a reason.
Companies like things like Web 3.0 and NFTs because they simply want to restrict or profit of secondary sales of digital goods. That's it. You don't own your identity or your data. You can just as easily be cut off from the related services. We've seen it with games and NFTs.
Financial transactions are generally reversible. That's a feature not a bug. A Web 3.0, just like with crypto wallets, will generally result in irrecoverable identities (ie wallets). Trying to build that into the contract through a consensus method of trusted contacts is just another potential vulnerability.
I really wish we, as tech-savvy people, were more cognizant of user benefits here rather than having some idealistic utopic view of a federated world.
