It’s been a while since, but from what I remember, my questions were generally in the same range as the framing highlighted by user seanrson’s above! I’ve also heard objections from people who’ve felt that predictions about AGI from biological anchors don’t understand the biology of a brain well enough to be making calculations. Ajeya herself even caveats “Technical advisor Paul Christiano originally proposed this way of thinking about brain computation; neither he nor I have a background in neuroscience and I have not attempted to talk to neuroscientists about this. To the extent that neuroscientists who talk about “brain computation” have a specific alternative definition of this in mind, this proposal may not line up well with their way of thinking about it; this might make it more hazardous to rely as much as I do on evidence Joe gathered from discussions with neuroscientists.”
