I sort of agree with you - BUT - twice now, I have gone to a camera store and picked up a mirrorless Nikon, and it felt to me like I was watching a TV screen. My impression was that it was awful, and when I stood in front of the first store, and “panned” the camera left to right, I almost felt “seasick” from the way the perspective changed. I’m sure that’s what my eyes see with no camera, or with my DSLR, but the effect is totally different. In my opinion, there is no substitute for viewing the real scene optically, with my eyes.
My Fuji can switch back and forth instantly with a lever on the front of the camera, between optical view and digital view. I like “digital” because it shows me so much more information, but again, it’s like watching a TV (for me). With optical, I see with my own eyes, looking at the real thing, not a digital copy. …which is why I love the D780, and why I prefer to use my M10 in “rangefinder mode” rather than using the Visoflex to look at a tiny tv screen. They all have a viewing screen on the back, but most of the time, for lots of reasons, I prefer the viewfinder.
This is only my personal opinion, but my friend Ray who bought the Nikon Z7 II now wants to get rid of it and go back to DSLR. He has different reasons than mine - he shoots birds, and doesn’t like the way the viewfinder works when taking a stream of exposures. I’ve never seen it, so I can’t say much more.
Years ago, I’d already have bought the Z9. According to what I’ve read, it is an incredible camera. From my point of view, the better DSLR cameras from Nikon (D780, D850) are much better FOR ME.
The focus speed seems “instant” on my D780. Press the back-focus button, and the camera reacts. I don’t know how mirrorless compares, but to me, it’s like comparing $4.98 to $4.95. To me, I consider them both the same, five dollars.
That is a huge part of why I enjoy my Leica M cameras so much!!!
My opinion - people stopped buying new cameras, as the current cameras were already so good. So, along with the magazines and internet, they tell people about this NEW technology, and switch over to it, so lots of people are now buying new cameras to be part of the new technology. Then, in a stroke of (commercial) genius, they change the lens mount, so those people who buy the new cameras will replace all their old lenses with new lenses that fit the new cameras.
A brilliant stroke of marketing genius! Now people are buying new cameras again.
The new cameras can take advantage of the new technology, and do things the older cameras can’t, such as capturing a zillion photos per second - but how many of us will actually do so - and after a day of bird watching, do any of us want to come home with thousands of huge raw images to sort through?
To me, the whole thing is a gimmick, to sell more product.
My opinion isn’t going to count for much, as I’ve been going backwards in what camera I want. My camera batteries typically are less than half used at the end of a typical day. My images are 24 megapixel, which is far more than I need.
The photo of the Empire State Building that @Joanna and Helen both love was taken with a 12 megapixel Canon S120 camera dating back to 2013. Why did I buy it? Simple:

It was my travel camera back then, and I still have it. It lives in my Mazda.
I can certainly agree that for shooting video, mirrorless cameras can be better than DSLR.
Maybe you’re right, and I am just an old-fashioned guy who wants good gear that is capable, but simple. I do like my new D870 more than my D850, and more than my previous Nikons, but I like my M10 more than any of them, especially so since I retired from shooting for publication. So take everything I wrote up above with a few grains of salt.
