That's a really unfortunate framing. The cat isn't out of the bag; otherwise, there wouldn't be efforts to scale up data centers to support forecasted demand.
The inevitability narrative is a self-fulfilling prophecy, and it ends if we decide not to keep telling it.
"The cat is out of the bag" doesn't mean the cat is gone, it means the cat has freedom. I read the GP as meaning "no single company can currently control the trajectory of AI." That's not unfortunate -- that's great!
With open models and the work happening outside of Anthropic and OpenAI, the cat is most definitely out of the bag.
> it ends if we decide not to keep telling it
That's wishful thinking, what are you saying, labs/people across the world will selflessly decide they're not going to pursue further research if we on HN stop saying it?
I think you are misunderstanding the meaning of 'the cat is out of the bag', although I also think the OP misunderstands it, too.
The saying means that you can't un-tell a secret... once a secret is known to the public, you can't make it a secret again.
I think the more appropriate saying would be a similar, but slightly different, one: "That ship has already sailed"
That one is more about "it is too late to do anything about this" and less about information.
