I've enjoyed Howard Marks writing/thinking in the past, but this is clearly a person who thinks they understand the topic but doesn't have the slightest clue. Someone trying to be relevant/engaged before really thinking on what is fact vs. fiction.
he clearly states he doesn't understand the topic.
But you don't need to understand to explore the ramifications which is what he's done here and it's an insightful & fairly even-handed take on it.
It does feel like AI chat here gets bogged down on "its not that great, its overhyped etc." without trying to actually engage properly with it. Even if it's crap if it eliminates 5-10% of companies labour cost that's a huge deal and the second order effects on economy and society will be profound. And from where i'm standing, doing that is pretty possible without ai even being that good.
I believe it’s you who is misunderstanding his positions here. He clearly lays out that he is focused on irrational optimism effecting the investment around the tech, not whether or not the tech itself is viable. His analysis was indeed well thought out from the perspective he is approaching it from.
