What this misses is all the regulatory capture that he’s been campaigning for. All the platforms have now closed their gardens. Authors and artists are much more vigilant about copyright etc. So it’s now a totally different game compared to 3 years ago because the data is not just there up for grabs anymore.
The data has to come from somewhere, and all of the outlets that were used to train ChatGPT, stable diffusion, etc. have since been locked down. Any new company that Sam Altman makes in the AI space won't be competing just on merits of talent and product, they will also need to pay for and negotiate access to data.
I'd actually expect this to get far worse going forward, now that other organizations have an idea of how valuable their data is. It's also trivial to justify locking it down under the guise of protecting people, privacy, etc.
