I don't target for Flash anymore since the past few years.
We got all the warnings to move away from Flash for a long time now.
It's not Flash fault. It's sheep users that hate because same one else also hate and browser vendors use that. We know and I believe that soon we will not hear anymore about Flash security issues, because Flash will not be the target anymore.
I switched from Flash to AIR years ago, predicting this end (a good decision) and started using HTML5 for small web applications, leting the most powerfull and time consuming developing to AIR.
HTML5 for Web and AIR for Desktop/Mobile.
The worst case scenario would be Adobe stop updating AIR, as will happen soon with Flash If that happens, I don't see our desktop applications stop working on macOS anytime soon and specially on Windows. The desktop bridge it's a proof of that.
ANE's can also workaround the AIR boundaries.
On mobile side it's not exactly the same, because from time to time, Apple (followed by Google), stop supporting new Apps or updates don't use the minimum SDK X version or architecture Y but seems that this is the top priority for Adobe (seeing what as happening before).
We can't have any garantee's, specially from Adobe but at least we also don't have right now the oposite so it's not that bad.
I would like to believe that with Flash definitive out of scope, Adobe can re-use his resources for AIR.
A suggestion if @liquidate check my post would be:
- Rebrand AIR and rename any reference from flash.* to any thing else (yes, totally break version documented).
- Rename the SWF extension to anything else.
- AIR for Windows 64 bits (already on beta with great results and ANE's support so almost done).
- AIR for Linux. Linux have a very, very small marketshare but this pass a image of desktop multi-target. See what others player, even MS (how would believe that a few years ago!), are investing strongly on Linux.
