By DNA, are you referring to DNA as its biochemical structure? Or rather, the science of genomics?
Because if we pooled every super-computer and ran it until the ned of time, we still would not be able to completely and precisely sequence the entire genome of a human-being, due to the hyper-randomness, unexpected-repetitivity, and ambiguity of genomics & epigenomics.
Most human genetic sequencing has been exon-centered (which constitute around ~1-2% of our DNA) while the rest of DNA is scrapped as "junk DNA", due to a combination of us either not devising ways to get them to be transcribed in the lab, or the fact that DNA does not need to be transcribed into an mRNA or protein molecule in order to be biochemically active.
The paper mentioned in this article appraised 80% of human DNA as biochemically active, and it was published in
