I see that this theatre story has gone on for hundreds of years. Theatre is always on the edge of death due to some innovation or other. In this case, it’s the little eyases but when movies were invented, they were foretold to be the death of theatre.
Probably when the Greeks did their thing, some kind of new mask was reported to put all the others out of business.
The web is probably the death of theatre. Also YouTube. Also email. Also projections. Also turntables. Also Kickstarter. Also everything.
But theatre, always in the process of dying, is also never dead, never dying, always fighting for breath, perhaps but kicking all the way.
