>I think it would be easyish to fill out another 10 reasons for what "can't" really means that are more common than "it is flat out impossible regardless of budget/resources".

Yes. But the skit isn't about that.

I often get impossible tasks from managers. Luckily when I tell them why they actually listen and aren't purposefully obtuse like the team from the skit. But the obtuse manner of the meeting is part of the comedy. Sometimes the management/sales/marketing team just doesn't get it.

The most common request?

"Please enhance this 92x92 .jpg logo x5-x10 its current size without lowering the quality of the logo."

My most common pushback?

"Sure. Get with their designer and get me the original file, be it .psd or .ai so that I can work with a larger resolution copy of the image. If they don't have the original file for their logo, you are asking for one of two things: 1) Recreate their logo or 2) The impossible. If (1) my answer is no. If (2) my answer is with modern technology, I can't."

I've also been asked to uncrop photos. Not as in "restore a backup from before we saved over it with a cropped version" but literally uncrop a photo.

I don't necessarily blame these people or get angry with them. I blame CSI and other investigative shows where they "enhance" a blurry photo to 4k crystal-clear resolution and read the reflection off of a button of a guys' jeans to read the licence plate of his car. They've been told this shit is possible by TV shows that use just-enough real tech to make the fake tech seem real to people outside of the loop.

The crazy thing is that the fake tech is also often actually real, but real in the sense that there's a recent academic paper where in certain specific conditions they were able to do what is being asked ask by using lots of math, domain knowledge, and custom programming, at a total cost of hundreds of thousands to millions of dollars when it's all done.

Does that help you in any way in a commercial setting? No, unless you are Google or Apple or the like and it's not a simple request but the basis of a new business division.

Are you talking about the paper where they replicate keys from the roof of a building across the street when the keys were on the floor some several hundred feet away from a photograph? :)
Not specifically, more just the occasional paper you see posted where they've found a way to recover missing data from surrounding context. I.e. something like reverse engineering redaction boxes from JPEGs by reversing a non-lossless algorithm twice, once to get the lossy image in raw form with redactoin boxes, and at that point again to determine what was likely under those boxes from the surrounding lossy compression as it existed before.

I wouldn't get angry with them, but I would certainly blame them for thinking something is possible which a small child should be able to tell is not. I would advise you avoid working with people who believe computers are literally magic, as your life will be much better.

Your domain experience is showing. ;) A small child doubtfully knows what pixels are, how computers represent data, how an image is actually displayed, and why you can make them smaller with minimal (meaningful) data loss but you cannot make them larger.

That part confuses lots of people. From children to adults to my grandparents.

Also photo restoration is black magic to some people - and a joy to my heart when I get the opportunity to restore a photo for someone.

Nah. I'm pretty sure I could have figured out that zooming in makes things fuzzy, just like if you hold it close to your face it doesn't any detail to a photo, at age 7 or so.

Photo restoration is more art than magic, assuming you're more or less drawing in the missing pieces.
