If there's one thing I know about binary, it's that 1+1=10. If there's one thing I know about basic arithmetic, it's that 10-2=8. So if you spend one energy unit, then spend one more, and have a net gain of 8, that sounds pretty perpetual to me.
Yeah, I'm not really getting the significance of the order of the Y-axis. If it's supposed to be the order of the majority of peoples' specialized device sunsetting, I'd say camera came before web browser. I still haven't sunsetted a desktop browser and haven't used a dedicated camera for years.
