I love the idea of using a desktop chatbot, but I would steer clear of anything that isn't strictly local since the privacy implications are horrific with Gemini, chatGPT and others.

On a side note, since GDPR was established, services have arrived in Europe later than it would in the US or some other places. But I'm guessing the coming regulation will just be more of the same, like local hosting, only for GPU and NPU processing this time around, but who knows.
