Hey Prithiraj,
Broader scopes!!!
AJAX has been used in common in web applications. Many number of sites are using the technology to implement number of facilities in a web page --starting from email validations to chatting. I am waiting to know the future scope of this technology. How will the paradigm shift from ajax will happen? How far can we push the walls of ajax applications beyond maps and chats? How far can we implement ajax on mobile? And how will prototype and scriptaculous help?
Well, er�
42!!! What an all-encompassing question! :-) It goes entirely outside of Proto/Scripty scope, it's just Ajax-related.
We're just seeing the beginnings of Ajax use. Yes, there are maps, and chats, and Twitter, and portals, and the like. But there can be so much more, once you get out of the request/response full-page reload cycle.
I can't quite predict how far this will go, except to say that yes, now that devices like the iPhone are here, mobile webapps are an actual path (just look at some of the apps we get there now!) And Ajax runs fine on those (37signals recently released an iPhone version of Campfire, which is pretty Ajax-heavy).
If a paradigm shift happens again, it'll probably be more dependent on other client-side techs than on Ajax, though. The only real evolution we can foresee for Ajax is cross-browser requests with the new authorization standards coming up. But SVG, Canvas, HTML5, client-side storage and persistence (like Google Gears) and more can combine to really turn browsers into powerful platforms.
As for Prototype and script.aculo.us, they'll keep doing what they've done so far: watch the trends, extract useful
patterns from real usage, and turn these patterns into nice, cross-browser, spiffy one- or two-liner idioms :-)
