If this was in a peer-reviewed journal, the reviewers would hit this very first sentence with a demand for extensive citation. In the spirit of generosity, I assume the authors have references. But the problem with starting this piece, in this venue, this way is that now everyone who thinks of themselves as having a stake in this DH thing is invited to see themselves as this "advocate" they invoke. In the vast majority of cases, they will not recognize the second half of the sentence as something that they have ever, or would ever, advocate. This may be intended as a polemic that will spark serious conversation, but with the very first words a lot of the audience that would be interested in engaging this piece sees a straw man and a misrepresentation. With that, the essay only reaches those who are inclined to agree with it in the first place. That now makes me wonder, in a less generous spirit, is this an effort to engage in a debate, or is this clickbait?
