> I have another pet theory on why the demoscene died.
It didn't die. Revision hosts hundreds of sceners every year. This year over 400 entries were submitted to the competition, including 40 full PC demos and over 40 tracked/oldschool/executable music entries. Even for small, local C64/Amiga parties here you have to race for tickets to these events.
We released a C64 intro outside a competition a couple of months ago, and within a couple of days it was buried in the inflow of new C64 releases on CSDB. The C64 scene is bigger now than when I got into it 18 years ago.

That didn't die either. Things don't die just because you stop pay attention to them. The notion of competing with Pixar is absurd; the terms of competition and markets are entirely different. Pixar makes movies for the mainstream to make money. Sceners make productions for sceners that may be more interesting to them than a Pixar production in an esoteric sense that the mainstream will not understand.
