Kris, did you see Solaris (by Tarkovsky)? Theres another Kris there, others treat for a fool. Just joking, the matter is not there. The matter is you shouldnt care about what salespersons are saying (in photography like in anything else). They are the morons of this world.
Although, while I consider digital as an evolution over film in print color photography (sorry, I have little experience with color slides, so no pertinent opinion about it), I also consider B&W as necessarily linked to film. The main distinctions (two of them) are in: grain vs. noise (for film vs. digital), and light and shadows (or volumes and textures) vs. colors (for B&W vs. color photography). SPs will tell you about CDs vs. vinyls, but these are only recording media, not expression means like film. The allegory is not pertinent, only manipulation (and what else would you expect from SPs?).
Again, a SP could tell you that B&W is death, so it is the film! Ha, ha, did sculpture died because of painting? How could it be: one looks to the world through light and shadows (or volumes and textures), while the other does it through colors. Or, more recently, did painting died because of photography? On the contrary, painting just reborn when photography took over on the figurative constrains. So, are B&W and film dying? Theoretically they should reborn, but there are these scams of the world (the SPs) who can artificially kill them (I would be a fool to denegate this risk).
