Yes that is a good point. It is not a perfectly airtight analogy. I didn't want to stretch the article out even farther by discussing other aspects of the comparison. The ways that it is similar is that it is distributed among all the cells of every member of a species. There is DNA that is the same in almost every cell of every living organism on earth. We do have after all have similarities with root vegetables and bacteria in our DNA. Another similarity which I didn't go into was the array of organelles and DNA translation/transcription protein strands which I would liken to DAPPs. In that they were developed independently using the open source code and implemented non-locally by various users of the core DNA code after that fact
