I’ve read that half of all brain ….stuff (lol sorry — I forget the stat) is for visual processing. Correspondingly, visual content is pretty important to humans, and video is essentially the peak of that metaphoric mountain.
While one particular monopolist owns huge swaths of video content online, it’s not the only game in town. But, ya see, this is where it gets more complicated. In order to find videos you want to watch, you gotta have preferences, the more specific the better.
