>Assistant stuff. Like you bark "order a pepperoni pizza from Joe's Pizza" and it happens. You take a pic of your fridge and say "order stuff to stock it up to my usual levels". Or book a flight, or buy concert tickets or clothes, or get media recommendations, replan a trip while driving if you change your mind and add a stop somewhere. Ask to summarize group chat message floods. Put on some music. Control smart home gadgets.
Frankly, this sounds like a potential nightmare to me. Almost certainly, the big techCos that today use algorithmic "customer support" to randomly flag, ban and screw with users for completely opaque reasons and little recourse will try running all of the nice things you describe. It's very plausible that sooner or later it will become harder and harder to do any of those things by more conventional, atomic means, making you rely ever more on integrated connections between product/service providers and these ordering systems (it's "convenient", you see?) only to suddenly find yourself flagged, blocked, or banned for any number of idiotic, blandly brainless reasons and shut out of the most basic elements of your daily life.
That people would readily agree to sign up for such dependence on these opaque things is a mystery to me, and I hope a huge pushback against it happens at some point.
If you think I exaggerate, bear in mind how often such things already happen on a lesser scale in a world where having social media, a smartphone and accounts with services like Google's becomes necessary in some contexts. Also note how often someone or another finds themselves fucked when these existing dependencies suddenly get shut down because some bullshit algorithm supposedly said so.
It's also bad enough that payment systems and banking can be cut off to people who (having broken no law at all) hold some politically controversial, publicly activist discourse, or that banking and certain basic services can be withheld in some bizarre way because you live a life in which your residency or other life choices are outside the average. To have the same risks apply for ever more minor reasons across a huge swathe of just living your life is a monstrously insidious way of marginalizing and homogenizing social divergence.
