In 2003, the human genome was first deciphered, and related expenditures exceeded US$3 billion. By 2030, human genome sequencing technology will be more and more perfect, the cost will be less than 100 US dollars. At present, we have applied genomics to medical fields such as cancer treatment, through the genetic composition of patients to treat breast cancer and other diseases. By 2030, genomics will be combined with immunotherapy to fight cancer by stimulating human autoimmunity, making cancer a treatable disease. In addition, genomic technology called CRISPR enables engineers to precisely group genes and synthesize various functional organisms in cell factories. For example, inserting appropriate genomes into bacteria and microorganisms can even make them produce materials such as plastics.
