Oh wow, what a topic. I have experienced this from all angles. I'm writing programming books in which I have to extend/combine the work of various philosophers[1], I am a huge fan of history, science, and philosophy, and hell, I just tweeted about this subject[2]
I agree with the general gist of what the author is saying, but I find that I have a lot of problems using the word "psuedophilosophy". If you want it bluntly, all philosophy is bullshit and trying to stick the word science in there does disservice to both. The longer version is that programming is applied philosophy: we meet, we learn, we define, we codify into a formal system, we use that system to explore the universe around us.
The longer version gives us a hint, a compass to find our way around in the bullshit maze (and I use "bullshit" affectionately. My only point is that philosophy is a terribly different thing from science). Where are we going? After all, I'd argue that philosophy is the mother of all sciences, including math. It's obviously critical to humanity. But in my formulation, coders use the process of philosophy to do something, agree, create, formalize, explore. We do philosophy all of the time, but we actually do it. We don't write books on it or spend much if any time quoting or hero-worshipping others who may have done bits and pieces of it 100 years ago or more.
Just this morning I ordered the Great Courses series "The Modern Intellectual Tradition: From Descartes to Derrida" I am extremely pumped to get started on it. Because of my books and my interests, I've ran across all kinds of philosophy groupies: professors, doctoral students, fans, grads who hate the subject now, etc. My take: if you don't study philosophy you're missing out on life. Some of the smartest people on the planet have spent their entire lives thinking about tough problems. Use that work. Having said that, most all of them only had a handful of good ideas and spent the rest of their career taking them too far. You have to understand that too if you're actually going somewhere with that knowledge. Otherwise you're just intellectually self-stimulating.
If you're learning stuff to go places you can always look back and ask "Where am I now that I wouldn't have been without this knowledge?" That tracks well with this author because his core complaint, whether he states it clearly or not, is that folks pick, choose, skim, and misunderstand great philosophic works as a crutch to actually understanding or teaching something. It's either a prop they use to make rhetorical points or it's a mask they use to cover up their own lack of ability. Yup, they sure do. And you can tell because when you get through reading them you're not left being able to do something you couldn't have done before. Instead your previous opinions are validated, just with bigger words and some loose-fitting historical anecdotes.
