That we still revolve around static, line-based interpreters from the VT100 era (over more intelligent CLIs or hybrid UIs like Oberon) is indeed rather quaint, and the proliferation of underdesigned programming tools also, but I strongly disagree with the author's claim that all these Unix programs are "[bullshit] not intellectually interesting in any way". Perhaps I'm one of the few people who actually likes to read the source code to the nodes in their /var/log/packages, but potentially getting involved with userspace system programming is not to be dismissed.
