And yet, just like the majority of essays on AGI, that linked essay is a nice survey of history, but once that history is completed the author implies they are going to discuss the history of AGI construction attempts, but never does. The article transitions into personal theory and just peters out.
Perhaps I'm short sighted, but until we have some implementation capable theory of comprehension - that universal ability of humans to observe any phenomena and mentally deconstruct it into separate individual and independent driving forces that combine to create the observed phenomena - until we have an artificial comprehension algorithm all efforts towards AGI are futile.
