First of all, my thanks to Josh and Daniel for developing frameworks that have made life easier for all of us.
We work a lot on 2d classic interactive, touch screens, etc. We develop in the Flash platform ecosystem (mostly gpu mode, although also sometimes starling, feathers ...) because it is the most optimal and agile in the current market. In the same way that in the past there were multimedia authoring platforms (that is, a program that allowed integrated design and programming, and that facilitated life for this type of projects).
In the current era, it seems that nobody does that kind of thing, and we do not understand it, because is has a market that allows you to earn money and it is not as complicated as a full fledged game (although we also develop small integrated games) ...
I understand the ones that say they change to Unity, or to html5 / javascript / react / angular, or anything else. But if people change technology they also have to change their "type of work", because with these other technologies it is impossible to develop a "traditional interactive" with many different screens in the same timeframe (or it is impossible at all).
I think that Adobe has lost a huge business opportunity, and I also think that the rest of the industry has never valued the type of projects that I have just commented.
Reinventing the wheel is one of the stupidities of the human being, and at least in the technological field it does so frequently...
