It’s a weird quote anyway since there is commercial, proprietary software for DNA sequence analysis. Just a few examples of companies in this space are Sentieon, Edico (acquired by Illumina) and Parabricks (acquired by Nvidia). And Michael knows this (they’re sufficiently well known, and his own research laid some of the earliest foundations that Parabricks would ultimately build upon) so I’m assuming the quote was taken out of context or he was talking specifically about his own lab.
