I am a bit disappointed in his neutral and stale argument, which upon first reading does seem polemical and controversial (though indeed reductive to the digital humanities field--especially in his characterization of digital data collection as the 'reverse' of non-digital literary analysis; how's that for black-and-white myopia).
But, he repeats the argument that contextualized readings must coincide with distant readings. Or, humans can work alongside machines--which is ultimately a fair argument to make, that the one should not replace the other and are in fact co-dependent. Although, his reading of Milton is original and innovative (or is it?); and is possible because of the rising significance of distant reading, which prompts my second, more distant reading of the article, which is that he's not really deadset against digital humanities as he would have us believe because of the fact that what he considers an original reading of "Areopagitica" draws from formalist analysis coupled with "matters of statistical frequency and pattern." In other words, he has reaped the harvest of distant reading!
Essentially in his repetition of an argument already made in the digital humanities and long-standing (though substantially unacknowledged and marginalized by his efforts on ephemeralizing digital scholarship), he poses as a critic who stands outside the field, and by extension is 'more qualified' to criticize. Which is of course, problematic.
Great article though!
