And look at it now. The fact, after everybody was saying that their core product was on the verge of extinction, that it managed to do such a spectacular recovery while keeping film as its core product should say something about the product itself.
the current Harman is engaging in trendy things
Every company does. It's a problem when the core product is doing so badly that you hope your trendy stuff will bring you much needed visibility and notoriety (generally doesn't work). It's not a problem if your core product is doing so well that you can afford to do trendy stuff to add to your notoriety and visibility without risking canibalizing core product sales.
One also shouldn't forget that strong companies can actually create trends — Nike being one of the best examples. Strong and bold companies actually influence the influencers, not the other way around.
Point is, without numbers, we know squat about what's going to happen with film. In such a matter, opinions are irrelevant. Either film is going well enough that it will last years, either it's not and we might as well throw all our beloved equipment in the garbage since it'll soon be useless. Only numbers can tell. The rest is either rose-glassed opionions or doom and gloom, both of which take us nowhere.
To me, only reasonable answer to OP is film is plenty available now, go out, buy some and enjoy yourself.
If insufficient and one really wants to know about the future, I'll offer this : film will officially die on June 5th, 2031. In the meantime, go out, buy some, and enjoy yourself
