It's an even more garbage take on where modern or even post modern philosophy has taken us in terms of understanding. He seems to think philosophy ended with Wittgenstein (apparently even ended with Wittgenstein's first book).
It makes me think immediately of how Maciej obviously felt about PG sharing his thoughts in his Hackers and Painters essay that made Idlewords write this response[1]. The ideas and concerns in the philosophy article merit much the same response.
If you're looking for a good introduction of where philosophy since Wittgenstein might take you and why it's still one of humanities best tools I recommend the podcast 'Philosophise This'[2]
