Over a hundred years ago, Babbage might have said: >We already have machines that are generally intelligent and require as much energy as a few coalgas lights. Why wouldn’t it be eventually possible to replicate them in brass and steam? My understanding of the argument of this article is that the conceptual design that replicates intelligence is what the industry has failed to generate today. Simply stating that it might be possible to create is failing to engage; the massive increase in compute power from Babbage to McCarthy didn't give us AGI, because they didn't figure out the right design to reason about anything in even a hundred times a human's energy consumption. If from McCarthy to today we still haven't actually found the proper recipe it just might be worth considering the point the article's making in spite of our other advancements since then.
