Tesla shows off prototype for terrifying robot snake charger

Everyday, it seems, we're another step closer to eventual robot dominance.

Tesla tweeted a video on Thursday of a quirky robotic arm prototype designed to charge up its Model S car.

The video, which was also shared on Tesla's YouTube page, aims to show alternative, smarter concepts around recharging its electric cars.

Elon Musk teased the concept on Twitter back in December 2014, saying the company was working on a metal snake-like charger "for realz." But this is the first time we've gotten a glimpse of the prototype, and it's far weirder than imagined.

The video is ironic, of course, considering Musk is known for (among more notable things) his genuine concern about an artificial intelligence uprising, saying last year that robots could become dangerous in the next five to 10 years.

Just last month Musk, along with Steve Wozniak and Stephen Hawking, signed an open letter calling for the end of an AI arms race.

The irony here, though, is not lost on Musk.

As of right now, the charger remains a prototype with no definitive timeline for a possible release.

Tesla will also release a public beta for its Autopilot features soon, which promise hands-free highway driving and lane changes. It's odd to have a public beta for a feature such as this, though one could (uncharitably) argue the Tesla Model S is a public beta itself.

If this mecha-cobra charger eventually destroys us all, we'll have Musk to blame. Otherwise, not having to plug in your car seems nice.
