Cold storage is for cheaply and compactly storing large quantities of information that doesn't need to be accessed often. Yes, in order for DNA data storage to work, we have to have a means of decoding it. I'm not sure how this is a criticism of this specific technology as this would apply to literally anything that we use to store information.

We can store data on anything. Even plant DNA. And every few years someone goes "OMG, what if we stored data in Ocean Waves!!! It's incredibly impractical and almost totally useless, but it's theoretically possible!" And then some BBC talking head runs a special on "Are Ocean Waves the future of data??" And says that within ten years you'll be loading GTA from the nearest beach and talking about data access for poorer landlocked countries.

Since we can store data on anything, the next question to ask is "Is it practical? Is it useful? Should I encode it on a giant gold disk with a huge sign, or embed it in the DNA of plants like a puzzle from a 90's adventure game?" So, what data would we encode this way, and what would we need it for? I'm just pointing out that while it's theoretically possible, it's not really useful.

The difference here being that DNA, unlike ocean waves, is a naturally occuring molecule that evolved to store information that is encoded and decoded. How then is it a stretch that this molecule could be harnessed to store digital information? Furthermore, you ask what applications it might be useful for, and I already said in my original comment that cold data storage seems like a possible application. I also stated that there could be issues with the technology that either make it impractical now, and may even make it an inviable technology.

You said that encoding information in plant DNA is "like a puzzled from a 90's adventure game" which seems to be a continuation on your idea from your original comment. I'm not sure why this needs to be said again, but yes, for an information storage medium to be useful, you need to know how to decode it. Once again, this is true for any storage medium, be it a vinyl record, a magnetic tape, a CD, or a solid state drive.

I'm honestly not sure what you're attempting to criticize about anything I've said. It feels like you read the first sentence of my comment and decided that it needed to be attacked because it showed the slightest hint of optimism about an emerging technology. Would it have been more interesting if I had just said "it wont work?"
