It would be interesting to know why you think that developing film yourself isn't an option. People think that it's harder than it is, even for color.

I mean, a "magic machine" would cost more than many years of lab services. It would use more expensive supplies than doing it by hand, especially because you wouldn't be doing the volume its designers expected. It would require a bunch of maintenance that's at least as hard as developing film. It would take up more space than any reasonable darkroom. It's hard to see why that would be an option when developing with tanks wouldn't be.

Also, digital is in fact a superior medium in 99.99999 percent of cases...
