Don't get lost in the tech scene sauce, programming is a small sliver of what people are using LLMs for. OpenAI's report in September pegged it at ~4% of tokens being for software generation. Sure Anthropic is probably 80% or something, but only a small sliver of LLM users are using Anthropic. The reality is probably even less if you count Google's AI overviews. We hate it, but I have never seen a regular person skip over it.
The question is if regular people will pay cell phone level subscription costs ($70-$100/mo) for LLMs. If so, then we are probably not in a bubble, and the ROI will have a 5-10 yr horizon, which is totally tenable.
500,000,000 people paying $75/mo is $450B/yr. Inference is cheap too, it's training that is ludicrously expensive. Don't be fooled by the introductory pricing we have today either, that's just to get you dependent.
And yeah, chinese models, but look at what they did to tiktok. No way they are going to let the Chinese government be peoples confidants and no way is more than 0.01% of people gonna home lab.
