Just so everyone is aware, this is another person who is part of the Stanford group that told us in March that "everyone has already had it, it's not very dangerous and this will all be over soon,". The previous "spokesperson" for the "we don't have to do anything to make this go away" bunch is John Ioannidis. But it looks like he stuck his head out a few too many times and was so completely wrong that he blew up his credibility. So the team apparently has subbed him out, hoping that people would be wooed by "Nobel prize winner, and Stanford professor" For the record, his Nobel is for Chemistry and he is a Biology professor. He's not an epidemiologist, or a virologist or an infectious disease expert.
At least the prediction is only 4 weeks, so in 3-6 months we will know one way or another if he's right or not. There will be another decline, for sure, and these people will claim all sorts of victories, before we head into Round 3. Google his name, see if his March & May predictions were right (he is credited for one: China's final numbers - but who actually believes China's numbers? I do concede he might have figured out China's algorithm for reporting, however.)
