For the last 8 to 9 years a lot of instruction from presentations to all out courseware has been produced using Adobe Flash. Now, there is a widening call for HTML5 to replace Flash as the primary way to deliver robust interactive content on the internet. Apple has long been against Flash and in favor of HTML5 making their hottest devices like the iPhone and the iPad Flash free citing performance and reliability concerns.

Will Flash become obsolete? I wonder whats the remaining shelf life for all of the courseware being developed in Flash right now.
