I kind of disagree that we will “build” goal directed AI. I think it’s something that gets discovered by accident, like life. Kind of like an accidental chemical replicator near a volcanic vent, we might happen to make a purpose built system that just happens to have other properties we didn’t intend it to, resulting in unbound activity. It’s much more interesting than a machine, we have a great deal of emergent strangeness to look forward to
