I think cameras are largely obsolete at this point and the market will continue to shrink. I have several reasons for thinking that. First, I'll give an estimate based on my own experience that about 95% of all photos taken are of a family member, pet, new car, or deep snow on the patio deck. I once worked for Fuji TruColor which would process something like 10.000 to 20,000 35mm rolls per night and that's about all I saw. Often photos of the summer vacation and Christmas were on the same roll. People needed a camera to take those photos but ALL of that is now done with a cell phone. That leaves only niche photography for dedicated cameras--kids' sports, "serious" vacation photos, and "arty' stuff. I'll add to that a hand full of professionals, also a rapidly declining market. It seems to be the older generations that are interested in cameras, and that group is declining daily. Younger people seem to have little interest in photography other than a quick photo to post on Facebook etc., and nothing fancy. Neither of my sons has any interest at all in photography and neither do any of their friends. It seems to be a generational thing. I don't see any advancements in gear changing any of that. Photography seems to be returning to the state it was in around 1880, with photography mainly done by professionals, artists, and upper middle class & wealthy people who had money and leisure time/travel.
As for me, I have not bought any new gear in over five years. I always buy used, a couple of years after introduction. Because of the rapid decline in value I buy digital stuff for about half to two thirds what it cost when it first came out. I now have a D850 which I paid a little less than $2,000 for. OTOH, I mostly buy historical camera gear and prices on that have been going up over the past 10 years. My last purchase was a Horne, Thornwaite & Wood FL=10 inch Petzval made about 1844. You used to be able to buy those for a hundred bucks on ebay. I'm looking for a good FL=14 inch Petzval that will cover 8x10 and those are now over $2,000. I've heard reports from distributors that "craft photography" is making a solid come back in the past few years, such as albumin and cyanotype printing. For the first time in decades there are commercially made dry plates available. I shoot those and have also been shooting wet plate since August. The future of photography is starting to look a lot like the past.
