I'm going to say 2 things that will probably piss off a few people, but I feel it's rather true.
1) Sometimes the type of people who can afford pianos like that will be rich ________ (use your imagination) that like it playing by itself at their soiree's and cocktail parties, despite none of them knowing how to actually physically play.
2) I'm pretty sure Yamaha had something almost EXACTLY like the auto-play function and record feature... like 5 years ago???
