I've thought about this myself, but it's an idea before its time that will fight a desperate fight against one big problem: quality. Quantity is easy. Quality is hard. People who cook for themselves want to choose the ingredients that go into what they're cooking. That's often the reason people cook for themselves: I decide what goes in my body.

I really, really want to know if the green bell pepper has three lobes or four, because they taste completely different. The person being paid minimum wage to shop for my bell pepper couldn't care less, but the wrong choice will ruin my meal. The convenience of someone else shopping for you, while helpful, is racked with such problems of selection, quality, availability, etc.

The problems created by people shopping for me, at least in my experience, significantly offset the convenience.

How to determine quality will become a very big deal in technology in our lifetimes. What's real? What's good? What's legit? I guess it already is. Look at the collasal cesspool that is Amazon. What do I buy? I don't know. I don't know what's good.

In 20 years, your bananas will text you that they're ripe and you should eat them, especially because your potassium is low. In fact, the bananas will order themselves. But today, with the quality problems so thick with muck and subterfuge, I can't even get the correct bell pepper delivered.

This quality problem is why Amazon bought Whole Foods and is about to go brick and mortar countrywide. You just can't solve quality problems with intermediaries at this stage of the game because those intermediaries have no incentive to care.
