Thinking a bit more, it would be quite handy to have a "power seller" AI for all my random junk. Spread it out on a table, pan a camera over it, then leave it to the computers until someone's willing to pay an amount for one of those objects that's worth the work of packing and shipping it.
This is a really cool idea. A sort of table where you just leave the stuff that you want to sell. There could be a dedicated tablet / computer where to interact with the AI (adjust prices, receive orders) and a little printer to print the shipping labels.
Until that AI can take the item, take photos, describe the item properly, drop it off a post office - I assure you, dedicated AI will only slow you down.
