I went to Google IO in 2014 and it was very exciting as a young engineer. Google Glass, Google Cardboard, Modular Smartphone, 3D space scanning tablet, Android Wear, and Android Auto were all announced there. Now it seems Android Wear never really took off and Android Auto is the only product that made it to somewhat mainstream. I'm not seeing much exciting experimental projects from Google anymore but maybe I'm just older and not easily excited.
