Other important quotes: "o3 still fails on some very easy tasks, indicating fundamental differences with human intelligence. Furthermore, early data points suggest that the upcoming ARC-AGI-2 benchmark will still pose a significant challenge to o3, potentially reducing its score to under 30% even at high compute (while a smart human would still be able to score over 95% with no training)."

So ya, working on efficiency is important, but we're still pretty far away from AGI even ignoring efficiency. We need an actual breakthrough, which I believe will not be possible by simply scaling the transformer architecture.
