Project Alice can do all that, other non spying assistants too, offline, we have conversion skills, and if not, it's really simple to create, still doesn't require online connectivity
A little bit of an misunderstanding. When I originally said alternatives, I was referring to alternatives to voice assistants like Phone Apps, Google Searches, math in your Head.
That being said, from watching demos of alternative voice assistants on Youtube and going down the rabbit hole of actually setting up Mycroft, Ada, and Project Alice; yes the experience is better with Alexa, Siri, and Google Assistant hands down. The setup experience is light years ahead of these projects and the performance/latency is also significantly faster.
That doesn't mean I don't fully support what you're doing. I'm just looking at the current state objectively.
