Artificial intelligence and covid-19: Can the machines save us?

While the human brain can process only so much information at a time, machines are whizzes at finding subtle patterns in huge amounts of data, and they are being deployed against covid-19 -- the disease caused by the coronavirus -- in ways only imagined in the past. Data scientists are aiming AI at some of the coronavirus's biggest mysteries -- why the disease looks so different in children vs. adults, what makes some people "superspreaders" while others don't transmit the virus at all -- and other, lesser questions we have made little headway in understanding.
