I have been asked by someone in late 40s why uploading a video takes a lot longer than uploading a photo.
They are not dumb people. They just do not know.
The onus is on the engineers to design for them.
"Does it take longer to upload 10,000 photos than to upload 1 photo?"
If a 40-year-old can not answer that question, then they are in fact - dumb.
