Google I/O takes place near Google’s headquarters in California
every year in the early summer, aimed at helping developers with
their work and announcing new products. The 2020 event was
scheduled to take place on May 12-14, but now Google has canceled
it due to safety concerns.
May 12–14 is the middle of spring, but I suppose that’s beside the point here. I’d now put the odds of WWDC being canceled at about 2 in 3.
