You, a person that already knows about this, will never get that from a short segment on a public radio show intended for a general audience that knows next to nothing about it.
It is intended to make that audience think about it differently, because they have not even bothered to think critically about this at a surface level.
The fact that these models (along with every structure in any society) embeds the biases of those that designed them seems to continue to elude so many commenters here though, so it seems they really need to keep hearing this too.
Also, the models embeds the biases of all the people who create content on the Internet. The designers biases come in to l look at with the prompt hacks put in place later to prevent the AI from expressing bad thoughts.
It would be nice if instead of harping on this point they actually told what they think the missing story is.
If they think that AI is missing certain kinds of thinking - by all means tell me what they are concretely. Like i don't know if i buy that lack of diversity in earlier AI research meant that the AI research only allowed certain kind of "thinking" (AI doesn't really match anybody's thinking regardless of race), but i would be interested in a well researched argument that it did and what those other kinds of thinking are.
I think the problem fundamentally is that these stories tend to be platitudes (lack of diversity = bad) but don't actually go deep into what that concretely means. Ultimately i want something that makes me think about the topic in new ways; you need to dig beyond the surface to do that.
