Self funding for indie developers would be great but I don't see this helping. We don't have enough filmmakers or (I bet) enough audience attention and desire for many more of these.
Completely understandable. It's an unfortunate aspect of humanity in general: the need for God(s) to worship and follow, as well as the need to be part of a group.
If we can't change human nature at its core, we might as well leverage it for something good.
There are plenty of computer things and people from the 70s and 80s which would make great documentary subjects.
Agreed - there's probably loads of interesting documentaries that could be made with people still alive. A movie on game consoles of the 60s and 70s would be great, imo. And there's probably some out there I don't know about.
It also helps to recognize the "human factor" behind the decisions being made with these tools (although YMMV on whether this documentary will succeed in doing so).
Tangential, but I think that's one thing "Indie Game: The Movie" did really well - it covered the indie game devs while also really humanizing them and their weaknesses.
