A perk of connected devices, or at least what gadget manufacturers will tell you, is they can receive over-the-air updates to keep your device current. Those updates don't always go as planned, however. In fact, they can go horribly wrong. Take a company called Lockstate, for example, which attempted to issue new software to its LS6i smart locks last week and ended up bricking devices. That isn't great.

In a statement to The Verge this weekend, the company said a "small subset" of customers' locks were unable to communicate with Lockstate's servers. Again, let me just reiterate: these are locks used to secure physical homes. Okay, I'll keep going.
