Re: An "AI powered cooking assistant"?
I suspect they're fighting to form the beach-head in the domestic "software helper" market. Whether you need an AI to do it though, hmm...
I could see a market for something that does the following:
a) user does meal plan, software produces shopping list from it's defined recipes (whether user defined, or server defined + user tweaks is moot) and the known remaining items in storage
b) s/w brokers deal with supermarkets/other grocery vendors, arranging deliveries and shelf-life expectations for the items being delivered - ordering from multiple stores if necessary/desired.
c) meat-sack receives delivery and does the manual labour of putting it on shelves/into cold storage. Probably need some mechanism to update s/w with shelf lives - e.g. embed use by date in an RFID/barcode that is easy to scan as you unload
d) s/w can then (re-)organise what you're cooking on a daily basis to minimise what you throw away, as well as perhaps suggest additional recipes based on what's in your cupboards if you're running out of inspiration (perhaps where the AI comes in)
e) when cooking, app can then send simple commands to devices such as the oven to set the temperature correctly, and do the timing
Barriers to entry:
a lot of this is simple to do in your head, or on a piece of paper - personally I might find it useful for something to warn me that stuff is going off in the fridge, as I don't remember the dates very well, but the market for this might be small
Scanning stuff in so that the s/w knows everything you have is not going to be easy as it probably requires food suppliers to create and adhere to a single standard of labelling that is easy for the consumer to use. RFID seems the best option here as you can read it from a phone, but some items such as fruit/veg don't have any packaging, so a solution to this would be needed. Barcodes can already be done (e.g. various apps that monitor your food intake by scanning the barcodes), but I think that's far too clunky a solution at the moment.
Overall, it can probably be achieved. Not sure it needs to be integrated into your fridge/cooker though - it should be a standalone app that can interrogate/control *all* the different brands.
I'm sure someone will try and do it with Blockchain Technology (TM) next...
