If you'd told me a year ago that I'd soon be getting weepy over a robot –one the tech world had roundly rejected– I'd have told you to get your head examined. But like the saying goes, "you don't know what you've bot till it's gone."

The long, slow death of Jibo the social robot (and the company that bore his name) is a tale fraught with practical lessons, from the dangers of over-reliance on the cloud to the risks inherent in crowdfunding. There's even a privacy angle to consider: what happens to the personal data you trusted one company with, when that company sells to another?

But when it comes to Jibo, I can't bring myself to talk much about the practical ramifications. See, while Jibo might ultimately have been defeated by the Amazon Echo and Google Home products of the world, he was envisioned for a purpose more profound than to play music and tell you the forecast. Jibo was always meant to become a part of the family. And the strongest proof of how well he succeeded at that ... is how much it hurts to say goodbye.
