The places where "animation that works better than text+images" is incredibly small
I can read faster than you can animate - speed it up!
Or I want to read longer than you animate - slow it down!
Text (+images) solves this perfectly - and has for millennia
If that wasn't enough time to move on, I don't know what to tell you :)
Laughably, they claimed this was ethical to prevent users from accidentally running insecure versions after they stopped patching.
I can still install Basilisk and run HyperCard stacks I wrote 30 years ago, but I can't run the dozens of games I wrote in Flash. It destroyed a good chunk of my life's work.
So your comment is rude. It's fine to move on and work in other languages, as I have, but to not be able to even show 80% of your portfolio because it was intentionally crippled by the company you rented the software from that you used to make it, isn't something you can move on from. It's been disastrous.
It's no different than what happened when the C64 when the way of the dodo
Or folks who built stuff for DOS, and never updated to Windows
Technology moves on
Languages and platforms get deprecated and/or die
And if "80% of your portfolio" is on a now-dead platform, I'd say it speaks more to you not wanting to do something new than that you happened to build a bunch of stuff on something now dead
I get that it sucks that stuff drops out of support/manufacture/etc
But it happens
You can be sour about it, or realize it's the nature of life, and move ahead :)
This might be partially a fashion thing: people want the flashy interactions less. I for one appreciate some boring text with minimal animation! Also away from games where animated interaction is part of the point, designing a good animation that works better than text+images is often not as easy as many think, and you need to contend with that before you attempt to implement the design.
As there are less people wanting to make the animations the tools that would have replaced the tooling for flash (but outputting SVG+JS instead), of which there were a fair few in active development at one point, have languished unloved and incomplete – so not only do fewer people want to make such animations but those that do want to don't have easy tooling to do so.
There are a couple of e-learning sites out there using interactive animations to illustrate their points, one often has sponsor spots on a couple of podcasts & video series I follow though I forget its name ATM. I wonder what tooling they use, if any (though I doubt it is all manually coded).
