That's how you get weird things like the AI determining that your favorite items are jam, baking soda and whatever you left at the back of your fridge to rot for six months.
It is easy to detect what's in your fridge. We have that today on some smart fridges.
The problem to be solved though is
- what's in your fridge
- what's not in your fridge
- what do you consume vs throw away
- what do you buy
- where do you shop
- what prices are available
- what's the best way to minimize cost and store trips
- what's your metric for how to balance that
Of those things, AI is really only helpful for determining the metric for how much money you need to save to add another grocery stop, and knowing that the orange blob is probably baking soda.
Most of the rest of that is manual inputs or relatively basic but tedious programming, and those are the parts that would be the most annoying.
I say this as a person who has repeatedly utterly failed to use https://grocy.info/ because actually recording what you eat vs throw away is painful.
This isn't a great AI problem not because AI can't help, but because the tedious part isn't the part it can help with right now.
