hive is the only thing out there that come close the idea of web3.
Actually we do not even know yet what web 3.0 is. Currently there is no obvious definition, but there are various ideas.
According to Werner Vermaak from CoinMarketCap,
Web 3.0 is the next stage of the web evolution that would make the internet more intelligent or process information with near-human-like intelligence through the power of AI systems that could run smart programs to assist users.
Does Hive has near-human-like intelligence? AI systems? I am not an expert, but I highly doubt it.
Web 3.0 is yet to come. And even Werner say this.
