It seems like the term "web 3.0" has been used for a while now and has been applied to different things from an AI-focused web to the more recent iteration where it's being used to describe the trend towards user-own decentralised services and blockchain applications.
While we've seen a few decentralised technologies emerge in recent years (mastodon, blockchain, etc) I'm quite sceptical of how far this decentralised movement will go. Aside from digital currencies, useful applications of Blockchain seem relatively niche and a significant push towards decentralisation more generally seem unlikely given the lack of economic incentives for the established players (MS, FB, Google, Apple) to allow users to own their own data and services.
I generally tend to be quite sceptical of tech trends though so I'm curious if there's anything I'm missing here or if there's something I should be looking into?
No, its bullshit.
As far as the actual blockchain tech goes, it is interesting and has its place. But people who just are stuck at "blockchain = currency" and are trying to get rich off it are probably holding it back because few are truly looking at it as a tool and finding good uses cases for it.
I have compiled my thoughts on my blog https://yash.info/blog/what-is-web3/
The main ideas of web 3.0 are - decentralization, privacy, trustless networks and community ownership. These ideas look good in theory but don't work in real world.
It is technically interesting, but most definitively over-hyped for a straightforward JSON-RPC client.
Personal Note: Tech aside, I don't like this vision of the web where everything is a transaction with a cost attached to it.
