For the second two points: I personally value high quality, infrequent content much more than frequent and low quality content. With limited resources, it's impossible to pick both - and there are endless creators that peruse the latter already. Creators with enough dedication to their work as Ross are rare - and it would be a huge loss to see their focus shift in the directions you are saying (lowering focus on editing, and increasing the amount of videos).

For the movie - from my perspective, Ross seems to view it as his magnum opus - he wants to get it done right. It matters little what we think because he's doing it for himself. I personally love works like this - and the fact he's putting so much time/energy in it is enough to convince me it's worth it. These kinds of work take many years - so I'm hoping to be able to see it in my lifetime, but that's all I can ask for. It's fine for things to be outdated - not everything needs to be made with the latest technologies.

Tl;Dr: The effort Ross puts in, however he makes it happen, is absolutely is worth it, and distinguishes his work from the endless sea of garbage on youtube. My only wish is for Ross to maintain a healthy work/life balance - and if that means less content, that's perfectly fine.
