"Amateur" does not refer to the lack of programming skills, but the lack of imagination.
The underlying problem with Tim Berners-Lee's web is that it was never built for developers. (This is in stark contrast to Alan Kay's web.)
Tim's web was built for non-coders who would publish on the web directly by dabbling with files containing their journals/articles interspersed with HT-markup-language: It's like 1980s WordPerfect and MS-Word, except they would use "<b></b>" instead of clicking on the B icon, and would save it as an open ".htm" format instead of a proprietary ".doc" format. The invention here is the "<a>" tag, which allows these static journals/articles to be globally interlinked.
And that's it, that's the entire web vision by Tim: his web is a mere global highway of interlinked static-articles. Maybe if you had the money, you can buy an editor like Dreamweaver, Nexus, Publisher, Citydesk(?), etc, which would help you generate all those "<b></b>" tags by clicking on the B icon.
..And we see how his vision didn't work as intended. Indeed, there are mighty red flags right from the start that the world had wanted way more than what Tim's vision offers:
These days, we have even more red flags like the rise of Chrome-OS-is-the-browser-is-the-OS (exactly what Alan Kay had intended the browser to be btw) and WASM / browser-extensions.
In contrast to Tim's web, Alan Kay's web on the other hand, is a dynamic web built for programmers: a global highway of interlinked dynamic-programs. Non-coders who need a "page" would simply publish one by using a program on the web. (And the program itself was obviously written by programmers, not HTML-dabblers.)
..This is exactly the status-quo of Tim's web in the 2000s, but if we had Alan's web, it will have been done in the 1990s: Instead of the world having "wordpress and friendster" only in the 2000s, we will instead have them right when the web started in the 1990s.
..Similarly, instead of having programs like Steam, Visual Studio, Warcraft, VM Ware on the web in the 2040s, we will instead have them right now in the 2010s. (The multi-decade delay is due to these programs already having been built for the OS-is-not-the-browser, thus reducing the economic incentive for them to be rebuilt on the OS-is-the-browser-is-the-OS.)
So this is what people mean when they say Tim Berners-Lee had killed the True Dynamic Web by pushing his "shabby static web" onto the world. Ever heard of the terms "web 2.0", "web 3.0"? They would have simply been called "The Web" if we had Alan's web instead of Tim's web. But Tim's web needs constant revision because it is so static.
Obviously, all hope is not lost, as the Web can be remodeled however way browser vendors define it to be. But the point is that all these "bleeding edge" stuff that they are "inventing" on the web now are stuff that has already been invented a long time ago. We could already have it all today, not tomorrow.
