I'm using AGI here as arbitrary major improvement over the current state of the art. But given that OpenAI has the stated goal of creating AGI, I don't think it's a non-sequitur to respond to the parent comment's question

> Are you saying instead, that concrete predictive algorithms need improvement or are we lumping the tuning into this?

in the context of what's needed to get to AGI - just as if NASA built an engine we'd talk about its effectiveness in the context of space flight.
