This only makes sense if OpenAI just doesn't believe AGI is a near-term-enough possibility to merit their laser focus right now, when compared to investing in R&D that will make money from GPT in a shorter time horizon (2-3 years).
I suppose you could say OpenAI is being irresponsible in adopting that position, but...come on guys, that's pretty cynical to think that a company AND THE MAJORITY OF ITS EMPLOYEES would all ignore world-ending potential just to make some cash.
So in the end, this is not necessarily a bad thing. This has just revealed that the boring truth was the real situation all along: that OpenAI is walking the fine line between making rational business decisions in light of the far-off time horizon of AGI, and continuing to claim AGI is soon as part of their marketing efforts.
Companies in the end are predictable!
