I can see Colour (both C41 & E6) going the way of the Dodo in the next few years.
B&W I am more confident about its medium term future (10+ years).
It has already been down-sized when the mass market moved to colour film in the 60s & 70s.
We who shoot B&W do so out of choice – not because everyone else is doing it in what you accurately describe as the “me too” mindless mentality.
I do think we will be paying a LOT more for our materials though, as we become a very much more niche exclusive/elitist faction.
