The Morning After: Alexa's new 'Drop In' intercom system

For what is probably the lightest news you'll read today, Amazon's new feature for Alexa turns any connected devices into walkie-talkies. While they could already easily send messages from one device to another, now you can ask Alexa to "Drop In Everywhere" and get a live line to all the devices in your house, useful for finding out who wants what on their pizza or getting someone to check for a package at the front door. Just… don't activate it by accident? Researchers have combined biometrics from Oura rings with AI prediction models to detect COVID-19 symptoms up to three days early with, they claim, over 90 percent accuracy. It sounds pretty incredible, but the science isn't just about wearing a bit of tech on your finger.
