Short reminder:
The human genome, with all its magic, is about 3,117,275,501 base pairs long. Source: Wikipedia

So, if we can do so much magic with 1 GB, that should be an inspiration to all software to do more, with less space.
Thank you for coming to my talk.
It is compressed by histones, except during cell division and when specific sections are expanded for reading and transcribing
