"Virtual" means "cancelled".
Christmas will be "virtual" this year for billions of people, for the first time. In other words, they will stay at home, not spend time together, eat alone, and look at photos or videos of each other on their phones or computers. But we can look at photos, talk on the phone, and eat alone any day of the year. Christmas is cancelled this year, just like Hivefest, and Burning Man, and just about everything else.
