The funny thing about this post is that the author tells us to get off our high horses and come down from our ivory towers... and then proceeds to make a series of highly conjecturable claims presented with no factual evidence beyond his own confident assertion that he's in the know. There's like, no chance that in two years he'll be advocating for his new new philosophy.
In the meantime, I'm left to wonder "Iain Dooley who?" and be glad that I'm confident enough not to read an opinion-as-fact article and assign it significant credibility.
PS: A good first editing step is to ask "does my opinion-as-fact blog post question the capacity and potential of a professional web designer to understand simple concepts like string interpolation, and could they find this insulting?" before assuming that you've got it all figured out.
