He also appeared recently on Sam Harris's podcast to a bit more more skepticism.
I thought he didn't break much new ground from his previous appearance on Lex's podcast in 2019, which I went back and listened to before listening to the latest one.
But...in saying that - listening to him again triggered a multitude of aha moments for me, and got me thinking about things like: "what is a dream", "how does deja-vu work" in the context of cortical columns, 1000 brain theory, predictive voting, etc.
I though his most recent explanation on how creating an artificial neocortex is not a risk in itself, but rather what you ask it to do. He was also adamant that giving an AI the ability to self-replicate should be where we draw the line.
This was very interesting when they previously discussed that topic but was months before SARS-CoV-2:

Great episode all around.
