I'm sure he's a genius in his field, but I'm sure he isn't a logistics expert either. We literally don't have anything close to that capability. A shortage of testing equipment around the world has been documented extensively. They're aiming to get, and this is according to the government a few days ago, 100k a day by the end of April. That's ages away, and i'd be surprised if they manage that. Even 100k a day would only cover 700k a week. We'd have to multiply that by just under 100 times to test the whole population every week.
I would love it to happen, but it feels scarily unrealistic. Hopefully more plausible ways out of this are mooted.
