Soap dish without an optical viewfinder

In the photo, the first digital camera without an optical viewfinder of its own production :)

I wonder how many more years of evolution manufacturers will need to completely abandon the optical viewfinder (such a small peephole). I mean not professional equipment but ordinary household digital cameras.

In fact, who uses them now? The battery does not save much. If the LCD breaks, the camera becomes an almost useless piece of hardware. On the modern active matrix, the picture always looks brighter and richer than in life. Without an optical viewfinder, the cost would be lower and the production process would be much easier.

Nevertheless, all manufacturers with enviable persistence insert a small useless crystal into all new models. What for? Or something I do not understand?
