Strongly agree with the author that the original prompt is much more substantive, but I think they're mistaken that "skin in the game" is a small motivating factor for human written text. It's the entire motivation: we all want to look like we've done more (get better grades at school, or get better compensation at work) while minimizing effort. We're not incentivized to produce just the substance, coz effort scales O(substance).
I would argue against “entire”. As an academic I (and I believe many of my colleagues also) take much pride in what we write - both the content and the prose itself.
