Five years ago Google launched Google Glass – the futuristic gadget developed by Google X division – the company’s intellectual department where engineers develop way-out ideas. Driven by voice commands, Google Glass had quite impressive functionality and was worn by celebrities and featured a fashion show. However there were two problems with it. The first was quite strange design that could make you look like a dork and the second one was the privacy issue. In the end, Google withdrew the device in January 2015.
