Is Flex/Flash Builder dead?

[aligned2009]

I don't understand today's announcement. Is Flex/Flash Builder dead, or does desktop development continue, or do I continue developing and everything will magically work in mobile devices with AIR?

I don't think because Flash Builder is not dead. For features are good. But I can not understand why does Adobe Air not work with Webgl if I am using TreeJS / Html5 than it looks like Html5 Games move to Air. I missed time of features of Html / Javascript. Why do you not develop ane for Html5 / Javascript for Adobe Air 18/19. TreeJs is good WebGL Framework for Game Engine with Html5. I am very hopeful for that. Thanks best greeting from Germany.
