In his post, Joel explains how the current state of AJAX web-app development has many parallels with desktop app development back in the 90’s. Joel makes a breathless prediction of a future event that will revolutionize web-app development:
Here’s another quote that seems to be talking about Flex/Flash/Actionscript:
Somebody is going to write a compelling SDK that you can use to make powerful Ajax applications with common user interface elements that work together. And whichever SDK wins the most developer mindshare will have the same kind of competitive stronghold as Microsoft had with their Windows API.
Sounds like it’s a good time to be an ActionScript developer.
