There are also hard mathematical limits stalling AI growth. Frontier models haven't improved in like a year despite being fed money by basically the entire global economy. Diminishing returns on steroids basically. They're already at the limit of what they can make, and going further gives a much smaller improvement in the model, and now I hear there might not be enough human written material on the internet to train them.
It also looks like hallucinations are inherent to LLMs and you can't get rid of them. It's a side effect of the model. What commercial applications are there then, if you can't guarantee the output? It's worse than a human for most things since it doesn't know truth from lie and will confidently say both as if they're fact. It also looks like prompt injection isn't something you can fully guard against either.
What's the value proposition when you can't trust the output and the model might give a massive refund or discount to a customer and the courts rule the AI speaks on behalf of your company?
