That's close to my thinking. I doubt the researchers came up with PEDOT out of nothing, or maybe they did and they're rediscovering some ideas. Perhaps it was considered a more fringe or exploratory idea to use PEDOT back in the 2000s, so it didn't attract much funding, but the writers for Deus Ex found some papers and thought it would make for good sci-fi. And it has, since we're seeing an article today on it's viability.
