I’m hoping Apple will pull out a miracle and able to measure blood sugar with the Apple Watch. With that data, people can make apps to do really cool things to help that person out.
Also it saddens me to hear "I hope that company X will solve Y" instead of "I hope some university develops a method to solve Y".
But if someone is interested (speak investment interested) in non-invasive blood glucose measurement feel free to inquire. Peer reviewed publications available.
