The same thing has happened with pipe organs. There, the cost of a physical instrument is much larger—modest instruments are well over six figures, with many instruments reaching $1 million. Digital organs have found a place in many venues—especially those, such as concert halls, that only use them infrequently. However, there is still a thriving community of builders churning out new pipe organs, and a bank of speakers still can't match the power of thousands of individual pipes.

I saw an organ in the Netherlands that dates to the 1700's, and has been played by many legendary composers (including Haydn and Mozart, IIRC). While it's obviously seen continuous maintenance, it's still playable and used for performances today.
