Meaning no disrespect to photographers, I'm starting to think that a probable outcome of all the AI investment is a sharp uptick in shovelware.
If we can get AIs to build "pretty good" things - or even just "pretty average" things - cheaply, then our app stores, news feeds, ad feeds, company directives, etc, will be continuously swamped with it.
I still find great value in the TCM cable channel. Simply because if I tune in at a random time, it's likely to be showing an excellent old film I either never heard of or never got around to watching.
The service they are offering is curation, which has a lot of value in an age of infinite content flooding our attention constantly.
The reason to take all 400 though as every once in a while one photo is obviously better than another for some reason. You also want several angles because sometimes the light will be wrong at the moment, or someone will happen to be in the way of your shot...
And sometimes it is even combining elements from different photos: Alice had her eyes closed in this otherwise great shot, but in this other shot her eyes were open. A little touch-up and we've got the perfect photo.
I disagree with the "only" part here. Imagine a distribution curve of photos with shitty photos on the left and masterpieces on the right and the height at the curve is how many photos there are to be seen at that quality.
The digital camera transition massively increased the height of the curve at all points. And thanks to things like better autofocus, better low light performance, and a radically faster iteration loop, it probably shift the low and middle ends to the right.
It even certainly increased the number number of breathtaking, life-changing photos out there. Digital cameras are game-changes for photographic journalists traveling in difficult locations.
However... the curve is so high now, the sheer volume of tolerably good photos so overwhelming, that I suspect that average person actually sees fewer great photos than they did twenty years ago. We all spend hours scrolling past nice-but-forgottable sunset shots on Instagram and miss out on the amazing stuff.
We are drowning in a sea of "pretty good". It is possible for there to be too much media. Ultimately, we all have a finite amount of attention to spend before we die.
