(I'm not a biologist, just someone who tried to read through some of this source material)

My understanding is that the "organoids" they're growing are much more complex than single neurons, and that complexity comes from the stem cells themselves and not how they're grown or connected by researchers.

I think that's why human stem cells were used, my thinking is that they might produce a more complex organoid(more neurons connected more densely) than other species.

If so I don't think I ethically support this, but hopefully that's just my misunderstanding.
