I won't be using these features, but I'm not sure there's cause for concern. The implementation seems very sensible and legitimately privacy-centric. The LLM runs locally and is meant as an very basic email proofreader. The crypto wallet is a likely an extension of the password management tech they've already developed, with transaction features that some people care about.
I can see why some people want these features, and I'm glad there are new alternatives.
Thanks, the stories I've read have made it hard to piece together this timeline.
