You don't see modern films as an improvement over old ones, and don't see the need for fine grain films. That's fine, but I have a different viewpoint. You talked about fine grain film driving taste and thus demand in the 1950's and onward toward modern T-grain film, while I think the process was really the opposite.
Just to nuance a bit, a we agree on certain points. Fine grain was not
needed—not in the sense that a longer-lasting electric car battery is needed for the electric car to truly become practical. Fine grain was
desired—as Matt eloquently wrote: "most of us felt that grain usually got in the way of the film doing what we wanted of them." I don't talk about "fine grain film driving taste", it's the opposite: changes in taste, brought upon by various factors, were part of the motivation towards fine-grain films.
Need implies a necessity. It
has to improve or it becomes useless (an electric-car battery that can only get you as far as 25 or 30 km) or obsolete. I think it's great that fine-grain and T-grain films exist—I use Delta 100 once in a while. But changing Tri-X was not a necessity in the sense that it would still be used today to great effet if it had remained the same. Would people buy it considering it would go against the prevalent taste? Maybe not. But then its change would be motivated by marketing, not by necessity.
Again, my point is that it's a significant change, not an improvement—much the same way the CD was a significant change from vinyl, not an improvement (
enter endless argument here). I'm neither for, or against grain. I like having access to variety and diversity—the idea that if I want grain I'll have it, and if I don't, I can also have that possibility. Essentially, it's the reason I shoot three formats, 35mm, 120 and 4x5.
If the idea implied in this whole notion of "improvement" is that all films should strive towards smaller and smaller grain because, well, I don't know what, then I do think something will be lost in the diversity and richness of the film experience. But I'll survive and still listen to the White Album. On vinyl. Or CD. Or Spotify...
