The idea is fine, but the inevitable outcome here is that Apple and Google do the same thing in their respective smartphones and this device (if it's even good at all) is obviated.
Good. It’s disappointing how bad Siri is. I don’t need it to be an LLM trained to know everything in the encyclopedia galactica… I just need Siri to understand basic sentence structure so i don’t have to reword something five times before giving up because i don’t know the magic word order.
I would be astounded, astonished, and amazed if Apple doesn't have Siri++ in development to do exactly this, but with more guardrails.
