Yes. LOL.
And yes, HTML 5 is the future. It would have been the future regardless of Flash, because Flash is a plugin that is loaded from HTML elements. The entire web essentially is HTML, and HTML5 just defines the next step. Most of the stuff you see that is "HTML 5" is actually due largely part to Javascript. That HTML 5 Quake is
heavy on Javascript. It would not exist without Javascript. And if you can do it in Javascript, you can bet you can do it in ActionScript (which is Flash's scripting language).
