I think it will be more like:
"Pixie, reply to that email for me"
"Pixie, book that car service for me and remind them they promised a free brake fluid replacement"
"Pixie order all the ingredients I need to make my wife her favourite dish"
"Pixel, buy everyone in my family birthday presents"
I will 100% pay for that capability, and as someone that uses GPT4 to basically do my job for me, it really does not seem that far off. And I do think Google has an advantage here over Apple or anyone else, not just in Hardware, but in the enormous amount of data and information they have about both people in general, and specifically me.
