> Pretty much everyone has failed. Football teams, film studios, politicians, the lot. It's like trying to catch the wind. It did work for the NBA finals AFAIK. And it worked for the 2020 MotoGP season, even though it wasn't a "persistent" bubble and people were allowed to leave the venue between events. But I don't understand one thing from the article: were all the people locked into the venue? Or would they go out eating? If they were locked in, what about the staff which served meals and such? Was it actually a bubble?
