The title this post makes it seem like John Carmarck is concerned about AI making CS jobs obsolete. But that's not at all what this is. This is someone else asking Carmack about his thoughts on this topic.
(Submitted title was "John Carmack: From a DM, just in case anyone else needs to hear this". A mod changed it to "I’m concerned AI will make CS jobs obsolete" but yeah, that changed the meaning. Sorry!)
Right, and his response is, while not quite the exact opposite of the title, tangential to it at best. He says that programming has only ever been a tool to create software for humans, so just studying programming as an abstract concept detached from product skills is not advised. He does not say CS jobs will be obsolete in the future — if I can read into it a little, he's implying that the completely theoretical CS approach has never been the right path anyway, and AI will make that more obvious.
