That one struck me as... weird people on both ends. But this is Musk, who is deep into the Roko's Basilisk idea [0] (in fact, supposedly he and Grimes bonded over that) where AGI is inevitable, AGI will dominate like the Matrix and Skynet, and anyone that didn't work hard to make AGI a reality will be yote in the Torment Nexus.
That is, if you don't build the Torment Nexus from the classic sci-fi novel Don't Create The Torment Nexus, someone else will and you'll be punished for not building it.
