Please give your thoughts about this technique that is being developed to record information into DNA as a harddrive: https://www.youtube.com/watch?v=gK3dcjBaJyo

What will the limitations be? Will we have biological hard drives in the future that can be used in "real time"?

What about what is mentioned in the video: using this technique to make "biological sensors" that can record information in real time for later recovery.

Do you think this relates to the "Histone code Hypothesis"
> "A study of about 40 histone modifications across human gene promoters found over 4000 different combinations used, over 3000 occurring at only a single promoter. However, patterns were discovered including a set of 17 histone modifications that are present together at over 3000 genes.[16] Therefore, patterns of histone modifications do occur but they are very intricate, and we currently have detailed biochemical understanding of the importance of a relatively small number of modifications."

is that how we act as sensors to store information in real time, using the histone code?
