15 years ago, I could reasonably write a search engine. Myself. 1 person. In a few weeks (modulo bandwidth and server farm). I write a program that grabs a web page, and reads out keywords. Today, if I grab a web page, quite often, that web page has nothing except for JavaScript code. That code grabs the actual content from the server, lays it out, and animates it. To write a web search engine, I need to write a complete JavaScript library.
At the time, we were talking about developing all sorts of agents. Things that would shop for you. Things that would find parts for you. Thinks that would remember what web sites you visited, and let you search them. Things that would track where in a long set of pages you were (blog, comic, etc.), and let you keep reading from there. It happened for a while, and then it died when the web became too damn hard. Writing anything that can reasonably see and parse web pages now takes many, many web years. There are only four or five organizations with that kind of resources (WebKit, Mozilla, Opera, IE, and internally, Google). There are countless things we just didn't even imagine.
It's like the DMCA. You notice all the innovations that happen, but you miss all the innovations it made impossible.
