I just experimented with mistral and Llama3 on my start9 and my mind is blown. Lots of false results, always need to double check, but I was particularly impressed by the ability to explain scientific knowledge. Below I asked "why is the sky blue, and give me the underlying physics equations" 
I don't think you got the point. AI is awesome self hosted or api accessed there is no doubt about that. The risk is teaching AI you don't own everything about you, your needs, your friends, your anything really. The big tech will use it for their purposes and the government will use it against you.
Fair enough. Training AI will always require a huge consulting infrastructure. But at least we can solve the server hosting and api issue with open source tools. Running AI privately instead of having a giant corporation collecting prompts data is also a major win
