A shame. There will be decades worth of games, animations and other creative and informative work that will disappear, or become significantly more difficult to access. I understand there’s efforts to both develop a more secure, open source Flash player alternative, and archive games etc so they are still usable, which I need to look in to.
Ultimately life will go on, as it did after Java applets, Shockwave player, Unity web player etc stopped working. But I do find it a bit sad when I’m reading an old web page and there’s just a box where a Flash graph or whatever used to be, or I try to play an old web game from when I was younger and can’t get it working.
But then, I am a bit of a data hoarder lol.
Edit: This funny pic that has been floating around sums up what I mean!
