This kind of small scale optimization is not really the best use case for AI anyway. Considering the actual cost of running that kind of code at a large scale... I'm not convinced the savings are worth it even setting aside the petrol issue.

AI doesn't need to be in the hands of consumers. It should be a step removed, working behind the scenes to make all those basic foods cheaper before you even go shopping. It should be optimizing supply chains, reducing production costs, and otherwise making us more efficient at a societal level.

Which, well, in some cases it already is. Sadly many companies just use it to optimise their marketing 🙄
