Point taken. Thanks. A lot of dedicated film buffs probably went the same way when digital came out - refusing to go with the “new“ technology. In my lifetime I probably won’t go to mirror less, just because I am so used to regular digital DSLR.
This is a good point!
I was working in the school portrait industry as a lab manager and training content developer during the period I call the digital revolution (1996 to 2010). When we went from film capture to digital capture of portrait images, MANY long-time film photographers gave up the business. They could not handle change. Whether intimidated by computers, or unable to assimilate detailed technical procedures, they retired, sought other lines of work, or, in a couple of cases I know of, went certifiably insane. Our workforce suddenly got younger, smarter, more versatile, and smaller.
The same thing happened in our lab. We had over 100 people who had been there for 20, 30, or even 40+ years. Only a handful of them took our rather blatant hint that they needed to shape up their skills or ship out. We offered free computer training at the local community college. We offered free typing classes. We offered training classes in the lab. But in the end, most of them did not qualify for the new roles we had in digital imaging.
Of course, that was just as well, because the new processes were far more efficient than the old. Then too, with the advent of the world wide web, photo sharing sites, digital cameras in the hands of the "Debbie Digital" moms, the iPhone and Android smartphone revolution, and the recession of the late 2000s, our market went to hell in a hand basket. We closed three of our four labs. Massive consolidation occurred, as Lifetouch bought up as many school portrait companies as it could consume. They bought our division from Herff Jones in 2011. But recently, Lifetouch was consumed by Shutterfly. Like waves washing sand castles off of the beach...
I get the idea that people in their 60s to 90s don't want to change. Heck, film's still around! Use that if you want to. Or use your dSLR until it dies. Used ones will be cheap in a few years, even if they quit making new ones.
Mirrorless offers dozens of advantages over dSLRs, but dSLRs have some over mirrorless, still. For many, the biggest is that they're paid for!
