One issue with YouTube is archival status. Another is provenance.
At some point it will be as easy to create fake videos as to create fake text. It is unrealistic to expect people who aren't information literate about text will be literate about video, but I hope that there's a way for journalists to move away from YouTube by then.
I was googling for baking videos the other day, when all of the sudden most of the hits I got was auto generated videos uploaded on youtube. They just had some panning stock photos in the background with text scrolling on top and super generic music, must be really simple to generate.
There were hundreds, maybe even thousands, of them from various accounts, all conveniently linked to each other making more of them appear as relevant in the rightmost column.
