For me I never was a guy to get in front of the camera. Especially since I'd rather be a low key guy off somewhere in the background. However I've learned to open up and share my life not only through writing but also more recently through video.
I just love creating in general. Writing, music, videos, etc. I find it to be therapeutic. Craft is something I take serious so as an artist I am trying to devote time to getting better.
Unfortunately some don't take honing craft as serious as others. It's one thing to put out content with the intention to experiment and get better and then it's another just to put it out because it is easy like you said.
Overall though I think video has it's place and the same goes for writing. I'd rather write than just sit and do a video which is why I am always thoughtful in my writings if I happen to do video.
