Personally I think everything has an effect on everything. I think there is something to be said about creating art from a work of art, and the inspiration that brings.
Canikon are performers, they get the job done. They are however big and bulky and dull as dishwater, but while they still outperform there will be a place for them.
Some mirrorless camera's are works of art that you WANT to pick up. They can't go toe to toe with 35mm DSLR's yet for one reason or another, but they are training hard and improving fast. Soon they will be a match for DSLR's which they already are in some applications.
I walked into a camera shop a while ago to buy a 3rd D800E. I did something I have never done before. I said to the assistant, I have no intention of buying it but can you get that fuji out of the display so I can have a looksee. That is something I would never even think to do if it was a dslr.
Fuji just know how to make beautiful cameras. Makes me want to pick one up and take beautiful pictures.
I think Zach explains it well.

Done the whole walk into a store to ask to see the Fuji things 3 years ago. It was an older model, forgot the name but it retails at £1k. My brother in law has one and I got to play with it too.
But you know what, they are no doubt a work of art and buying one because you like it for the design, that's fine, but buy it knowing you are not getting the best for your money in terms of what comes out of it.
Photography for me is about the pictures, I share my pictures, I don't share my camera, I am not a collector of cameras. That's what is more important to me, by a long shot.
Consumers will buy lots of compacts.
Professionals will buy DSLR.
Consumers who think they are getting DSLR performance in a smaller body get mirrorless.
People who has more money than sense buy a retro looking mirrorless costing £3,000.
As for can a camera be a piece of art? Yes of course it can, a piece of paper can be a piece of art, anything that is designed is a piece of art. It might be a crap piece of art but art nevertheless. The only difference is desirability, exclusivity, price, heritage and name.
People buy mechanical watches costing £10,000 and thinks its a work of art. Funny that 50 years ago it wasn't seen that way, not until Quartz came along and got cheap, as all electronics do, so SWATCH (Swiss watch maker) had to market their more expensive, desirable watches as "works of art". Before Quartz, a watch is a watch, like a frying pan is a frying pan, something you use to tell time, just as something you use to fry an egg, then all of the sudden it was seen as more upmarket, like why would you spend more money on something that does it less good? Because it is prettier than that Casio and because we tell you so.
So art is merely a perception, especially when it comes to a mass produced item. There is nothing unique about most of these £10,000 watch. There is no precious metal or gems, most of it are stainless steel or leather, some even have rubber straps, the glass are the same glass that can be found in a £300 watch, it will not keep better time as a £10 Casio Quartz. People buy it for the design, the heritage of the name behind that company. They certainly don't buy it for the time keeping aspect of it.
Anyway, can a nice retro looking Nikon be a piece of art?
Sure.
Will it be remembered like a Picasso?
Not a chance.
It can however giver the owner joy to hold something that is like it came out of the 70's with modern technology, I guess we call that novelty.
