At this point I'm pretty convinced that no new gigacorp will be emerge out of this generation of AI (LLM and vision models). OpenAI will have to continuously bring their A-Game to stay 6 months ahead of everyone else. There is durable moat that they could hide behind in sight as of now. Of course they would like to construct a regulatory moat but it doesn't seem like there is a clear majority for this.
I'm pretty sure and happy that this will probably turn out as a large consumer windfall. Actually comes right in time to counteract the strong inflationary forces that come with de-globalization and declining efficiency due to increasingly basing the economy on gov spending.
