Oh Google Glass, the type of technology that you’d seemingly find in Sci-Fi movies the likes of “I, Robot,” “Minority Report,” or “Terminator.” The device is still a taboo and seems a bit silly to some people, but we can’t ignore the trend. Wearable technology is a growing market, with the rise of fitbands and smart watches from seemingly every tech company, but when, if ever, will Google Glass hit it big?

Business Insider’s “Business Intelligence projected at the beginning of 2014 that Glass sales would reach roughly 800,000 units by the end of the year. Al Sacco, a reporter for CIO.com criticizes that those numbers seem a bit ambitious, since the Explorer Community Facebook page for those who have purchased it only had 38,000 members in June of this year. When the device went open for public sale in the U.S. in May, there was a generous number floating around of 300,000 owners of Glass. The process of coming to this conclusion is less scientific than Business Insider’s, albeit, but it still has some merit.

Whether or not BI’s numbers are accurate, their projections still aim for over 20 million units sold by the year 2018. That’s more than the population of the state of Florida. Their reasoning is that Google will target the early adopters in fields like “medical training, scientific exploration, and photography. They in turn will popularize Glass and other smart eyewear among wider populations still unsure about the appeal.”

If Glass’s appeal does catch on, hopefully the later models’ numbers can be as successful as the iPhone 3G. In the first quarter of 2008 alone, the iPhone 3G sold 2.32 million units according to statista.com. That’s almost three times as many units sold as Google Glass has had in its first two years of sales.

I personally believe that wearable technology is a rapidly growing market, and although I am skeptical of Business Insiders’ numbers now, I do agree with their projections for 2018. It took a while for people to wrap their minds around smartphones and the iPhone, but when they did, the market growth was so exponential that it’s now one of the most promising markets in history. It’s going to be an exciting few years, and I can’t wait to see the once science fiction ideas of the past become our everyday encounters.
