The algorithm makes sense to me, in that on my main PC I pretty much exclusively watch nerd shit on youtube. Tech stuff, 3D printing, machinery, motorcycles, that sort of thing. Youtube therefore probably assumes I am male, so in my Shorts feed seems to be comprised of about 90% boobies, and 10% clips about guns.

But then the algorithm doesn't make sense to me, because on my living room PC we pretty much exclusively watch cat videos, bird videos, and videos-for-cats (the ones with all birds and squirrels and stuff), How Ridiculous, and Gavin Free. The Shorts feed there is also roughly 90% boobies, but in fairness the remaining 10% appears to be cats.
