Movie theaters will lose popularity but the theater experience cannot be reproduced in the home at least for the foreseeable future.
I don't see many films in theaters because many films gain nothing by being viewed at the theater. I often see films in like Interstellar, Dunkirk, Blade Runner, etc that are an assault on the senses and have a lot to gain through theater viewing.
The question to me is- will people care? There are plenty of examples of people shirking quality for convenience.
