Harvard professor Calestous Juma and author of Innovation and Its Enemies: Why People Resist New Technologies, says the technologies that are hardest to discontinue are those that:

Are part of a larger ecosystem such as those used frequently in the home, have repair shops, and a market for used and refurbished devices.

Are seen in cartoons and animations from our childhoods.

Are imagined as being useful to survive the zombie apocalypse, such as safe rooms and $365$ day food supplies.

Are physiologically addictive.
