CES 2022 preview: The metaverse, NFTs and a self-driving tractor? Plus more virtual events

The massive CES technology show will go on this week in Las Vegas but the annual summit, like many other recent events, is being hindered by COVID-19. The Consumer Technology Association (CTA), which runs the CES, had planned for a hybrid event to run Jan. That's a step forward from last year's CES, which was conducted completely online during the coronavirus shutdown as vaccines were just being deployed. However, in the days leading up to this year's conference some big name exhibitors have bowed out. And some media outlets have canceled plans to cover CES in person.
