Arthur C Clarke has (as usual) beaten them to it. In "3001" he describes a thing called an "Autochef" which produces meals on demand. However by then they've lost their taste for meat and regard Frank Poole (a rescued Astronaut from 2001) with some disdain when he remembers the meat of his previous life.
And of course the food replicators had this beat on 60's Trek episodes where they skipped all the messy details and converted energy right to food matter of whatever choices desired (as long as the food data was in the computer's "tapes")...or maybe it was the Jetsons win where both fuel for transportation and food were all conveniently reduced to pills. Utopia if it were not for the push-button-itus maladies of that scene.
I will try printed meat when it can have green eggs printed along side it, sam I am.
Something tells me that a variation on this theme is in our future whether we like the idea or not. Already we have "pink slime" which is meat that's been mechanically chewed off it's host and more or less recreated. We have water and flavoring being injected into meats and who knows what else.
If it is deemed safe for human consumption and is less expensive to produce, it will end ina a store near you.
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
