This is neat, i didn’t know about it.

The article gives the example, though, of giving your phone to someone you specifically dont trust. The most dramatic example is an insurance card or ID to the police when you get pulled over. The best answer there is just dont ever do it.

This pin setting says the security on it is pretty weak and to not give it to people you dont trust.

The article doesnt talk about changing prices based on demand, it is about changing prices based on competitors’ prices.

And yea, if Target increased their prices when Amazon increased, then they would just all be higher. Then they could do it another round and another round until one of the companies decided they were at the limit.

If the two companies talked to each other about this, it would be illegal collusion. But instead they have code automate it without an explicit conversation, which may not be illegal but certainly makes our lives worse.
