10 Hugest Inventions Since the Year 2000

9) Bluetooth

Bluetooth is another communicative technology that changed the way we speak with each other. Fifteen years ago you may have laughed at someone who had a little bud in their ear and appeared to be talking to a ghost as they walked by. However, nearly everyone with even the faintest use of phone technology will use a Bluetooth-like device sometime during the year.

Bluetooth enables people to wirelessly call and talk with a hands-free device. A phone can stay in a pocket as people walk, run, or drive and they can have full conversations without ever holding the phone. The safety side of Bluetooth is still debatable, as distracted driving is distracted driving whether holding a phone to an ear, or being hands-free. However, there is something to say about a technology that enables you to speak to someone as if they were in the vehicle with you.

The technology has also saved millions of lives of people who were not capable of reaching a phone to report an accident or serious injury. Simply by speaking into their Bluetooth device they were able to contact emergency services.
