Could an update mean a Google Glass resurgence?

Google Glass, an experimental and extremely expensive wearable that took the tech world by storm a few years ago, resurfaced again this week when it received its first software update in nearly three years.

The update, released on Tuesday, isn't terribly exciting: in addition to bug fixes and performance improvements, the only new feature is Bluetooth support, which means Glass can now be paired with input devices like keyboards.

As TechCrunch notes, the last Glass software update was in September 2014, so this week's update might be reassuring to Glass owners who thought Google abandoned them. Still, adding Bluetooth and a few unnamed enhancements is not that reassuring, and everything else about the Glass seems to indicate that it's headed for extinction: the support website is pretty bare bones, and the Google Glass homepage simply reads "Thanks for exploring with us. The journey doesn't end here."

Google didn't immediately respond to a request for comment on whether we'll see more Glass updates in the future.
