Now maybe help maintain instead of going chase some closed source proprietary holy cow that may abandon you just the same as flash and have a fully future proof implementation...
Yes, you could reimplement a flash player using HTML5&friends, but it takes a considerable amount of work to get it accurate and performant.
There's an experimental project by Mozilla to do just that, called Shumway
The latest commit on their GitHub repository is from 2 years ago.
There was also an swf-to-html project by Google called Swiffy and a GNU implementation of Flash Player called Gnash
not sure if you know already, but gnash is a free software replacement for the flash plugin(hence websites detecting you have flash). But a certain major change (I'm not sure what) in the flash plugin made gnash development slow and hard. So websites will tell you that you have outdated Flash. PPAPI by Chrome devs is the only up-to-date alternative to the Adobe Flash Plugin but it is closed-source.
Try Gnash or Lightspark. Gnash is good. Lightspark doesn't work everywhere yet.
I also use Yandex Browser Beta on Linux. It comes with Pepper Flash.
Note that Youtube switched to HTML5 as default.
Good point. People have written emulators to run the proprietary software written for video game consoles. If Flash games are worth being preserved, people will write software to support them. Gnash exists but doesn't support all the features.
Perhaps. I haven't tried it myself though.
here is a tasvideos forum post on it. http://tasvideos.org/forum/viewtopic.php?t=20547
It specifically requires 3 things. Linux, libTAS, and Gnash.
libTAS is a framework for doing TAS's on many games in linux. It also works on emulators run in linux.
Gnash is the GNU implementation of flash. And allows you to run flash movies and games on linux.
It seems to work for many flash games, but apparently it can be an effort to properly setup, and can depend on the exact game.
It's not like this content will become inaccessible overnight. We'll still have old versions of Flash, and failing that we still have Gnash. There are probably Flash-to-whatever converters too.
One can only hope that the few remaining sites will remove it going forward, but historic sites that need it won't be lost.
Hell no:
many non mainstream browsers will still support it
you can always use an older browser version ( just stick to just flashgames with it, don't go about your daily browsing with an out of date browser )
you can download standalone version of flash player ( called flash player projector ) to play games you downloaded.
There are already a few open source alternatives being made ( like this and this )
GNU Gnash is about your best hope.

If it's anything like some other GNU projects, you could come back in 10 years and it won't have changed much.
We could feasibly port Gnash to the Vita. It can flash files up to v10.
A flash browser extension is not happening. Even Chrome is dropping support for Flash later this year.
