The smartphone had made a lot of jobs in photography redundant or obsolete. I was one who was made obsolete after working for 26 years in the photography business. Most of the things you see made done in a smartphone were things once needed people like myself, well paid professionals, to make the images look great. No more. These days, computational A.I photography make everything look somewhat professional just by buying an app.
Smartphones like the Huawei P30 Pro uses technology and software that are very similar to what you can buy from Topaz Labs. The Topaz A.I series, like Sharpen A.I, Denoise A.I, Gigapixel A.I and Adjust A.I are somewhat built into the software matrix of the Huawei or even the latest iPhone X series of phones. So when you took those photos, the smaller sensor isn't an issue anymore once the image is processed through computational photography. So when you look at the images by pixel peeping, you think that you've got a better camera from the Huawei P30 Pro vs the $1000 traditional camera. But the problem with those $1000 traditional camera is that, all cameras made by Canon, Nikon, Olympus, Sony, Leica and Hasselblad plus Fuji do not come with A.I computational photography software included. You have to buy a separate computer with a powerful GPU and a multi-core CPU plus get equivalent software like Topaz. I bought a Mac Pro 5,1 "specifically" to run the Topaz suite of software and that cost a total of $1000. And my GPU, which is the RX580 isn't the most powerful either as it takes about 2 mins to process a 16MP or 20MP image per computational task. I have both a 1" sensor and a m/43 camera and I am totally impressed after I put those images from a 1K camera through my Mac Pro. They just look so stunningly beautiful; so much so that I don't need full frame.
A 1k camera using Topaz A.I products will smoke any 1K smartphone in terms of images. They will look much cleaner, more detailed and have better dynamic range thanks to the larger sensor on 1k traditional cameras. The problem is, you need a thousand dollar computer or a bit more with a better GPU and software to post process it like the Huawei or iPhone which has those things somewhat built right in. As smartphones get even ever more powerful, it will threaten the 2k to 3k cameras.
Traditional cameras will always have a market because they offer interchangeable lenses and maximum creativity. But the days where cameras are a must in photography has long since passed. Most people will use a smartphone as their cameras. In fact, when I upgrade my old iPhone, I will no longer use my 1" Sony sensor camera anymore as it just adds bulk to my light travel kit and process my images when necessary using Topaz A.I software to get the best out of those phone images, but I doubt I need them.
Unless you are planning to print 40x60" prints like you're printing 4x6', most people don't really need a Nikon D850 nor the new Sony A7R4. Most people are happy with 11x14" Walgreens or Costco prints which the smartphones will duly print well on. And besides, why do anyone care about missing a few details here and there, because most people don't really bother to print their images. Even if they do, the prints themselves look pretty good. Critical prints with critical detail are good only for gallery prints which command for big bucks. I see that. But I don't see why you need to store all those detail in the images unless that what you want -- to entertain yourself that you had captured a master piece which when shared online goes from a high value to a zero monetary value these days.
