I agree that the work of Lacan, Derrida, Baudrillard, and their contemporaries do deserve study and contemplation. I've done it, and I learned
a ton from it.
The problem that these generators address is much more circumscribed.
Rather, it is poking fun at the people who do not understand these literary giants, but claim to.
This kind of obscurantism is often used to hide the fact that the author doesn't fully understand what is going on.
A hallmark of deep understanding in any field is the ability to simplify complex concepts and relay them to a reader efficiently. (I'm not a physicist, but Brian Greene can explain String Theory and particle physics in a way I understand. Why can't someone do the same with Lacan?)
For example, Zizek is excellent at this. (As are many others.) If you read his papers, they do not sound like this. He uses the buzz-words necessary, but he makes straightforward arguments. And IMO, that's why he's been successful--he's helped get Hegel, Lacan, and other writers' complex philosophical ideas out to a very wide audience, efficiently--by writing good, quality prose.
Compare that with much of what comes out of undergrad/grad student writing classes, and I submit that there is a huge difference. And that's what this is poking fun at. Just my 2c.
At its deepest level, it is a question of inequality: some people are able to BS their way to tenure, fame, etc., by writing like this--because they understand the system better than others who weren't as well groomed through upbringing, good mentorship, or other circumstances. Writing this way is a strategy for certain people who know how the game is played: it has worked, and will continue to. But that's a problem, and it's one worthy of mockery.
