The happy go lucky Down's people, however, are just what you see of them in media. That's a tiny fraction of the entire population with Down's, which consists of a range of horrible and crippling mental and physical disabilities, in addition to increased risk for diseases like early onset Alzheimers.
Giving a child a life like that feels cruel and heartless to me.
That's curious, because in my opinion YouTube recommendations haven't been any good since 2009. Instead of getting interesting, strange and niche content, I'm bombarded with videos that have >100k views, feature clickbait titles and thumbnails and are generally incredibly low effort content.
Methods that work better for a population as a whole might not work better for a large subset of that population, and might even cause users to stop using features entirely. The lack of transparency in recommendation algorithms combined with the homogenizing effect of distributing low-quality content this way is something I find somewhat depressing.
