So you don’t buy the meme that AGI would prefer to operate on blockchains rails because of their universality, security, programmability, etc.?

AGI will decisively obsolete blockchains, but it's likely it'll be obsolete for all but 1 or 2 usecases well before then (few years) as non-blockchain P2P, ZK, trust infrastructure develops

Where blockchains are limited to only objective strict consensus, AGI(s) can achieve complex, subjective consensus - "AGI will use blockchains" is a silly, nonsensical meme not unlike "telegraphs will use internet" 

Valuable cryptoassets like BTC and ETH will live on after blockchains are obsolete because, as I've said a hundred times before, this is a socioeconomic movement, and tech is only means to an end. The tech will be replaced, the socioeconomics will live on.

Caveat: "AGI" is in itself a meme, so I'm assuming it'll do what people popularly expect

I'm lacking context, but why do people think artificial general intelligence will use human made blockchains?

That's like ants saying we'll use pheromones for navigation instead of gps. Their limitations are not ours.
