It's hard to balance innovation and useless over-engineering. Of course I'd like to wake up and have a freshly presses glass of juice ready to be drunk. But the technology isn't there yet (or it is but it would be way too impractical). Juicero is a middle-ground solution that doesn't really solve anything. It is easy to mock them for their failure, but if we never try to innovate we will never reach the point where I can wake up and (like in Wallace and Gromit) have my freshly pressed juice fruit ready.
The company that was trying to make the smart cup that told you what you just put in your cup seemed pointless.
