DNA Fountain – Capacity-approaching DNA storage

Another viewpoint is that in an academic setting, there is no reality-check, professors rarely loose their jobs, students are free, and operating budgets are small enough to be overlooked. The only people judging are your peers, who often have the same kind of nonsense scheme. Even if it doesn't work, and is completely useless, the idea of DNA storage is guaranteed to never die.

The data storage is almost totally irrelevant. When you improve DNA synthesis by 3-4 orders of magnitude, you make it dirt-cheap to synthesize whole custom genomes, hyper-optimized for anything you wish. (Currently, the state of the art is synthesizing an E coli genome takes multiple years and a large international collaboration.) CRISPR only lets you do a few edits at a time at most, in some parts of the genome; imagine being able to do tens of thousands of edits as easily as 1 edit. At that point, you're hardly even 'editing', you're designing organisms as a whole. The Church lab has some astounding proposals for things you can do when you are able to synthesize a whole genome, like cleaning out all the retrovirals, movable elements, recoding the genome for total viral immunity, on top of the obvious stuff like eliminating all mutation load or increasing specific traits by dozens or hundreds of standard deviations. The mind boggles.

It's actually not hard to do. In theory, a single PCR reaction with only two primers could copy the entire data set in a few hours.
