I highly doubt New York theatre- or live theatre in general- will return ever again. I believe all theaters around the world will be demolished in no time. Theatre is a dying art form anyway, and it had lost much of its appeal before this crisis. I may sound like an extreme pessimist, but this is unfortunately true.
If the world were to return to some sort of "normalcy" in the future, it would have no face-to-face interaction, meaning no funerals, weddings, family reunions, hugs/kisses/high fives, conventions/assemblies, sports, live television, religious gatherings, and theatre, as well as many other forms of leisure which were prominent not so long ago. Schools and businesses will all be online. I am an introvert at heart, so I hope the world comes down to this.
Good riddance to live theatre until the end of time. You've been an uninspiring, money-grabbing distraction for years on end, and you probably won't be missed by many.
