The translation feature has been very useful, though it's not an LLM. Still a neural network though. Saves me from going to google translate when browsing websites in e.g Russian (drive2.ru or whatever turns up in google search every so often when looking up obscure information on some cars and european oils that bitog forums don't see as much).
It entirely depends on what the AI does and if it's opt-in, opt-out, or forced on you. Opt-in local AI with sensible features is actually a good thing IMO.
