Just for debate sake (because I tend to feel as you do) letm e take the other side (although we could be arguing semantics around the world simple.... so leaving that aside)
Is making a web page simple? Yes.
Is making a web page do cool stuff simple? Yes. And it's way cooler than the logo and basic (and worse) of my youth.
IS "web development" simple? Not in the slightest, as a generalization.
The web is the UI component of an application. That application could be as complex as any other - but instead of a simple visual toolkit for our GUI, we have to understand a bundle of technologies that is constantly changing (HTML, CSS, JS), plus the end user platform (browser) and all it's quirks.... now throw mobile in,now throw in that some understanding of the network itself is required.
Thing are more open now, information is more readily available, and there is certainly a lot to choose from.
Further, there's the audience - you can now publish your apps to the world immediately, you don't need to get recognized and published on paper or through a publisher. So a simple, silly little game hacked up in javascript/html5 by a kid (yay kid! You did more than I did at you age, keep it up!) has more impact and visibility than did similar feats by similar kids back in the 8-bit days when they figured out how to make my CRT do things God didn't intend it to do all for my amusement.
