While the performance of a computer chip per dollar is doubling every twenty-four months, the costs of sequencing a genome have fallen by a factor of between five and ten times a year. Even if that precipitous fall in price–performance slows down – perhaps aligning with trends elsewhere in computing for a further decade – sequencing a genome could cost as little as $30 by the late 2020s. That alone would transform healthcare, although according to Raymond McCauley, who previously worked at Illumina, such a conclusion is unduly pessimistic. His view is that by 2022 sequencing a genome will cost
