I'd argue cause...something like technology's version of the "trickle-down effect". Some displays will require advanced engineering skill, but I'd wager that the majority do not. When you're working at the leading edge of technology it's much easier to evaluate multiple competing technologies and compare them on the merits. When you're given a $5000 contract to produce an advertising display in 2 weeks, you're going to go for the most Google-able solution.
