On a "price awareness vein" - I've thought that a killer app would be a phone app that runs in a grocery store, it detects costs, brands, and sizes, and overlays two things 1) the option that is cheaper per mass and 2) whether there are cheaper options in other stores. Bonus for "this no-name is the same as that brand-name".

Imagine waving your phone, or having on your VR glasses and getting this feedback "instantly".

Plus, you can sell what you learned to sellers so they can out-compete one-another (and drive prices down for consumers).

In a sci-fi world this would turn grocery stores into Faraday cages quickly.

Maybe not useful for the Doordash generation, but the majority of human life can't afford such.

That sounds like living in hell, tbqh, especially with the selling data part.

The discovery part is anything but. I was trained to recognize scams in grocery stores (the on sale smaller is never cheaper then the bulk item... until rarely it is) early on by my parents. Few people recognize just how bad this is. Educating folks with somethign that does it for them first is a first step.

But yah, completely with you on the "sales is hell" part, that bit was for the startup bros.
