Honestly, PCs are not ready for local LLMs
The auto-translation LLM runs locally and works fine. Not quite as good as deepl but perfectly competent. That's the one "AI" feature which is largely uncontroversial because it's actually useful, unobtrusive, and privacy-enhancing.
Local LLMs (and related transformer-based models) can work, they just need a narrow focus. Unfortunately they're not getting much love because cloud chatbots can generate a lot of incoherent bullshit really quickly and that's a party trick that's got all the CEOs creaming their pants at the ungrounded fantasy of being just another trillion dollars away from AGI.
