in the paper, we say 1.5mg per petabyte at large scales. we only encode 650kB or so. this seems a little sensationalistic. we are far away from being able to do 1 petabyte of arbitrary information.

Wait, 1.5mg per petabyte at large scales? Wouldn't that mean a gram could hold (1000/1.5) 667 petabytes and presumably scalable to many grams (eventually)? I understand it's only 650kB right now, but the density is obviously still incredible.

yes. density is astounding. that's why it's in science i presume. mostly because people forget how dense dna information really is.

you are either the most humble senior author ever or jerking all our chains. possibly both. congratulations either way.

this is my first senior author paper; i imagine i'll be more haughty after I start teaching a few classes.
