And after the Baroque era, organ culture was never a big trend in the classical music world. Symphonic music and opera takes most of mass media attention nowadays.
And now the role of religion is diminishing in the Western world. It's not uncommon for churches to go out of business and transfer their inventories (including pipe organs) overseas where the religion is still strong.
The good news is the Internet and technology. It allows us to connect like-minded people easier than ever before. Because of this, the idea of organ art can spread.
Another good news is that there is no longer only one mass media. Everyone has a full-blown video studio in their pockets now. And everyone can choose to have a channel to spread ideas worth spreading.
Will the organ art survive this century?
Every day I'm doing at least one thing to make sure it will.
