Google isn't pushing through with its annual Google I/O conference, not even the digital event. With shelter in place requirements imposed on California, the company decided to cancel the event. Google said in a tweet, "Out of concern for the health and safety of our developers, employees, and local communities—and in line with "shelter in place" requirements by the local Bay Area government—we sadly will not be holding an I/O event in any capacity this year."
The wording used in the series of tweets seems to confirm that there won't be a 2020 Google I/O event, so any announcements to be made will either be done later or through developer blogs and community forums. Those who won in the drawing of tickets this year will be automatically be invited for I/O 2021.
