Why is Web3 not the future?

I'm curious to understand, why is it that some people argue that Web3 may not be the future of the internet? Are there fundamental flaws in its design or implementation that make it unsustainable or impractical in the long-term? Or is it simply a matter of preference, with alternative technologies offering similar benefits but with a different approach? It would be interesting to hear your thoughts on the potential limitations of Web3 and why some may question its status as the future of the web.
