The only real farming left in the US are large industrial farms.
Quit parroting that left wing lie. It's total bullshit that one 5 second Google query absolutely disproves.
If you're encoding data on film, but you still need a digital camera or computer to read it, you still might be screwed and the data might be inaccessible. By microfilming the source docs, all you need is a light source and a magnifying glass -- both of which are decidedly analog and low-tech compared to the method being used for this project. Plus sliver halide microfilm lasts at least 500 years if properly stored. Either you're taking the digital component out of it, or you're not. Having a digital requirement in there might make the data inaccessible in a post-electricity, post-digital world post-apocalypse.
Waste not, get your budget cut next year.
