tech illiterate

Someone who doesn't know anything/very little about technology. Sometimes they end up throwing around buzz words (like high-speed, big data, machine learning, IoT etc.) in an attempt to make themselves look smart - much to the dismay of the geeks watching.

Steve: "This new smart watch has 1TB of ram, a machine-learning CPU processor, 15MB of high-capacity SSD storage and 10MB of mobile data. Pretty good, eh?"
Dan: "eh..."
Steve: "Oh! Did you know that the watch also comes with a state-of-the-art big data analyzer?"
Dan: *sighs*
Dan: "Steve, your such a tech illiterate - did you know that?"
