This kind of gets at the reason why I think a lot of tech articles/blogs about what the future will be like are just terrible. The wants of someone who is driven enough read and write about the bleeding edge of technology are very, very different from the general population. Like this author says, most people don't want to run their own web server, but I'd go even farther and say, most people don't really care about decentralization or even data privacy. Getting most people to care about privacy and decentralization is like getting a kid to eat vegetables. They know they should, but the alternative has more short term benefits. I think most people care about ease of use over almost everything else.
People who write these articles need to be thinking about the middle aged woman who still calls every video game system "a Nintendo". There will always be some users for technologies like web3, but until you can clearly demonstrate to that woman that this new technology has value and is easier to use than the status quo, you're never going to get mass adoption.
Connecting this back to web3, we're clearly not there yet. Almost anything being done on web3 is slower, more expensive, and more complicated than its web2 alternative. We may or may not get there one day, but until we do, I don't see web3 being anything more than a niche product.
