That completely ignores WHY people use MF/LF cameras in the first place. Just upsizing my photos, regardless of how sharp they are at a given size, isn't going to give me a reason to switch to small format digital. No software package can replace the act of using a view camera in the field, nor can it replace using a 150 year old portrait lens. Yes, yes, you can always emulate those things in software, but it's an emulation, and there are definite limits to what corrections to perspective you can do in software without losing resolution and introducing distortion. Get it right in camera, rather than fix it in post. I'd rather take an extra 15 minutes before I click the shutter than spend an extra two hours doing the same thing but on my computer afterwards.
Exactly.
There are dozens of different reasons why photographers use medium or large format. Photographers are individuals, and each has his own individual reasons for the medium he uses.
What the OP has posted will not have any effect at all on medium and large format film usage.
Medium and large format film usage are
increasing! Part of my job is market research in the photo market (both digital and film). Therefore I know for sure.
The number of LF camera manufacturers has increased recently, because of increasing demand the prices for lots of popular MF film cameras are increasing significantly, too.
Lots of photographers have "digital fatigue": They have to sit in front of computer screens on their job the whole day. And they don't want to continue that in their rare leisure time. Film photography is the perfect alternative.
No one in the photo industry is discussing a potential "end of road for MF/LF". No one.
What is really of a concern is the collapse in digital camera manufacturing: The digital camera market has lost almost 90% of its volume in the last decade. Here are the numbers:

The backbone of camera manufacturing - compact cameras - is already almost gone. The number of sold compact cameras is meanwhile even lower than that of ILC cameras.The first time in about 60 years. Dozens of Asian OEM digital compact camera manufacturers have already given up and left the market. Former big players like Epson, Casio, Kodak and Samsung have left the market, too.
And the big question in the industry is: Which digital camera manufacturers will be next?
Because all know that the strong decrease in demand will continue in the coming years. All the forecasts of the manufacturers indicate that the total number will fall below 9 millions units p.a. And that market size will be too small for all of the remaining manufacturers. Nikon expects the ILC market to collapse down to only 3 million units p.a.! Much too small for all of the current producers.
There will be one chance for some of them: Keeping above the critical level by adding film camera production again, because there will a future increasing demand again.
Fujifilm is already doing that very successfully: They are producing about 20x more instant film cameras than digital cameras.
The chance of film is possible for some manufacturers who can relatively easy add (further) film cameras to their portfolio: Leica, Nikon, Canon, Pentax, Fujifilm, Hasselblad.
In 3-4 years the OP will pray for this additional film camera production because it can keep the manufacturers and the digital camera production alive.
