Amen. Cinema will never die, but the standards have definitely slipped.
I've had to tell managers (who leave the projection booth after merely flipping a switch) that a film stopped running.
We sat in the dark for like, 6 or 7 minutes before I said to myself "nobody's doing jack".
The managers are usually the projectionists now (unless it's an IMAX theatre). They train them to flip a switch or spin a platter or whatever they do now instead of changing reels. Efficient? hardly.

Remember that lore about Stanley Kubrick famously making his projectionists turn away from the screen after they begin the film?
I love that.
Kubrick was a DIRECTOR.
