I think it’s possible that last year was just unusually slow for people (possibly pandemic-related?)
I looked at 3B1B (the only Youtube explainer series I’m familiar with) and since 2015 Grant has produced ~100 high quality videos, which is closer to ~20 videos/year than ~10/year.
I’m not familiar with the others.
and could plausibly be ~20% more productive in a year in terms of the main, highly-produced videos
I feel like this is low-balling potential year-to-year variation in productivity. My inside view is that 50-100% increases in productivity is plausible.
Yeah, I agree about how much variance in productivity is available, your numbers seem more reasonable. I’d actually edited it by the time you wrote your comment.
Also agree last year was probably unusually slow all round. I expect the comparison is still comparing like-with-like.
