Yes, but the most significant barrier is with the first, not for the followers.
I think it's a Tesla situation. Tesla did very well, and I believe OpenAI will be too, but everyone else will catch up and then some.
Once the first model rolls out, knowledge from that model would eventually disseminate. And it doesn't even need to be on a human level, industry and academia experts could probably make very good guesses on what's going on behind the curtains - and follow up. And we already have plenty of good models on our hands, some even open sourced.
