Let's not kid ourselves, AJAX is a very minor technology. It may be widely used these days, but there's not that much to it, conceptually.
It's the kind of thing that even a moderately experienced programmer can understand within 10 minutes, and then have used it successfully another 10 minutes after that.
Asynchronous HTTP requests weren't a new idea in the early 2000s, by any means. I'd used C and Perl libraries that allowed for just that back in the 1990s. The only thing novel about it is that it could be done from the browser, using JavaScript. Really, AJAX is more a testament to how limited the browser and JavaScript are, rather than some great new technology.
