The next big problem on the horizon for the piano is that piano technicians are also a dying breed. Sure, you can get someone to tune it, but that's fairly easy to do myself. The problem comes when a damper is stuck, some notes need voicing, etc. Even the old geezers that know how to do this stuff don't want to bother. They just want to come to your house, do an electronic tuning, and leave with $140.
Even if you're able to spend obscene amounts of money on a fantastic grand, who wants to do that if there's no way to maintain it?
