Not too long, did read :)

If you want your software to be experienced by as many users as possible, there is absolutely no better route than a web app. The web is the most efficient, most pervasive, most immediate distribution network for software ever created. Any user with an internet connection and a browser, anywhere in the world, is two clicks away from interacting with the software you wrote. The audience and reach of even the crappiest web application is astonishing, and getting larger every day. That’s why I coined Atwood’s Law.

Atwood’s Law: any application that can be written in JavaScript, will eventually be written in JavaScript.

Writing Photoshop, Word, or Excel in JavaScript makes zero engineering sense, but it’s inevitable. It will happen. In fact, it’s already happening. Just look around you.
