Meta has a massively profitable social media business with an impenetrable network effect, so they're using that to subsidize the research. Whether that's a good decision or not is above my paygrade, but it's sustainable until something changes with the social media market.

I don't know what "moving the goalposts" means. Why were the goalposts there in the first place? The interesting questions here are whether OpenAI can sustain their current cost model long-term, and whether the revenue stream is sustainable without the costs. We'll see, I guess! It's fascinating.
