They aren't sending your biometric data all over the internet. They verify your identity on device and then send a token around.
For an object to be on the internet, it doesn't need an internet connection.
Example: I'm looking at a pen right now. I'd love to be able to dive into this pen and see it's specifications, who made it, maybe even the history of pens of this design. But I don't need the pen to connect to the internet for that, I just need either an RFID(or similar) tag or a slick recognition algorithim. Then I can just point my phone or wearable or whatever at the pen and get all the information that I want.
So yes, lets put the connected toasters back in the closet, but don't throw the baby out with the bath water.
do we want to rely on results that are likely skewed because the test subjects were also taking heroin, methamphetamine, and cocaine?
There are tests for that.
