High quality personalization is hard to demo.

Imagine a system that does an extraordinary job of personalizing a map for someone.

You take a real example generated for one person and show it to that person as well as others.

To the person it was generated for, it's magical, perfectly calibrated for them.

To everyone else, the result just looks bland and unremarkable.

The person whose context it's based on has the "key" in their head, all of the personal experiences that help them recognize how well fit it is to them, and it "pops" for them.

The other people just see an ordinary result that seems bland or even random.

It's not possible to demo personalization to a given person without personalizing it to them.
