You have all these recipes, but no real great way to determine the best version of something.
There are certain techniques (simple techniques) that'll make steak and coffee taste better, but they're hidden amidst a vast empire of information and useless knowledge.
There's another aspect that people rarely think about:
100 years from now, will humans still be cooking food? Or will that be regulated to machines?
If so, you'll need a way to keep track of all the recipes and what humans enjoy the most. You need a way to filter what's good from what's great.
And when you zoom out, it's a problem that's common to GoodReads, Netflix, and information in general.
How do determine what people will like? And how do you grade it?
