I think because sometimes it's pointless to waste time thinking about future when it's unpredictable. And yes, I do live my life that way.
Predicting the future is an exercise in abstract thinking. It's one of the distinguishing characteristics of intelligent life, including animal intelligence. We all do it. Even you. Even if you don't realize it.
Would you by choice step in front of a fast moving train? No? Well, that's because you can accurately predict the future. Predicting the future is often just a simple exercise in recognizing potential cause and effect. You put on shoes every day, right? Carry a spare tire on long trips? Don't walk into dark alleys carrying fistfuls of cash? Don't run with scissors? (That was your mom was teaching you how to predict the future...)
I have had many wonderful things happen to me in my life precisely because I refused to ignore what was going on around me and, using that information, successfully predicted the future. And I have also avoided many bad things the same way.
Far from pointless, I might associate the refusal to think about the future as something akin to walking down those same railroad tracks wearing a blindfold and earplugs. Sure, you can do it. And it's guaranteed that your future
will arrive. But you must be absolutely willing to place the outcome of your future into the hands of that fellow driving the train. And to recognize that his are not, and will never be, your hands.
Analog photography in 20 years? Just apply the same cognitive reasoning to the question that you already do every day for everything else.
All signs point to it being reduced, but still practiced. Both color and b&w. It won't be Kodak or Fuji. It might be Adox and Harman and Ferrania. Or maybe even just Harman. But it will be somebody.
And the cameras? Well, it took 30+ years for me to have my heavily-used (including with a heavy-duty MD2 motor drive) Nikon F2 serviced for the first time. The technician matter-of-factly reported that all of the mechanisms, including the shutter speeds, were still within factory tolerances. And my current favorite camera, a 47-year-old Crown Graphic, looks, feels, and works like brand new.
I think we're good...
