I figure expectations/behaviors will shift once this becomes the new norm. That 5-second birthday present or shallow prospectus summary will become obvious pretty soon after a wide uptake and nullify any advantage.
I mean, all those auto-composed photo slideshows universally suck; you've seen a couple (per vendor), you've seen them all. Easiest way to tell - music. Second easiest way - goofy title, some photos don't match the purported theme.
As for the prospectus video - that I suspect would fly, and will fly for many years to come, because whether it works depends entirely on how well this guy can sell it. Being able to talk off skimming the summary of the Cliff's Notes of a book, without the teacher realizing you didn't read the actual thing, is a skill people tend to master in high school.
I'm pretty sure most teachers could tell you which of their students actually did the reading.
If they could tell but did not, they were derelict in their duties.
I chose to believe our teachers were overworked, and some of us were good enough at extrapolating on the go and selling it, than that our teachers cared so little they'd just play along.
