The article appeared in the monthly magazine of IEEE, the Institute of Electrical and Electronic Engineers, so the audience is not completely non-technical.

However, having seen IEEE's decline first-hand over the past 25 years, they are clearly dumbing things down a bit to cater for all types of audiences, including non-EEs. Even their website now just uses the slogan "The world's largest technical professional organization for the advancement of technology", and many of its articles now fall into the styles of those of retail science magazines.
