This week, Neil Young, the greatest rock and roller of all time, released his version of the iPod, the Pono, at CES. The L.A. Times, equally enthralled by electronics buzz, predicts the future in food tech. Stuff like a smart fridges that generate shopping lists for you and suggest meals based on its contents.

And a magic negative ion shooting, bacteria fighting knife. I look forward to the efficacy data.

These ideas may seem far out, but they’re already being worked on: A smart knife that tests food’s freshness, nutrient content and bacteria level when you cut into it and keeps it fresher by infusing it with negative ions.
