My favorite computer in the video is the sequencer. I find it fascinating that it can identify a virus in just one hour. I also think it’s really cool that it can test and get results in one hour. It tests DNA for viruses. I think computer science can change the world by helping to create vaccines for viruses. The person who Spoke about this is named Vida. She talk about the sequencer. Overall computer science is changing everything and making easier for people to do there jobs.
