I did feel that the yellow warning sign was a bit much. There was also a line about it not being for designers. As somebody with both design and engineering backgrounds, I felt less enthusiastic right away — mostly because I dislike buckets being enforced. It encourages people to put themselves into one over the long run, which in turn has a tendency to stunt their progress. It’s also odd when any educational resource (higher ed in the US being a great example) introduces itself by trying to be inaccessible. It feels counter to the professed goal of the institution / article.
Anyways, I guess I felt the comment above is a valid thing to discuss if it could improve other people’s efforts to write similar pieces.
As an aside: ironically, the article is fascinating from a design perspective. Just not the particular bucket of design the author was thinking of when he wrote that line.
