Origin and Evolution of the Globstar

The roots of the glob, the kleene star, actually come from a formalization of neural networks.

I feel old! I never knew this existed; probably because my Unix shell experience was mostly built in the early 90s and zsh was not often used or distributed in large academic installations at the time; I believe ksh cost a licensing fee as well, leaving us plebes hoping for tcsh (ibm usually had this available) or bash (elsewhere), and apparently the * syntax was turned off by default for most of these.

An interesting side note in the blog post is the back and forth over whether to follow symlinks - the accepted answer is currently ‘no’.

Since you can hard link a directory in posix, I wonder why the back and forth and why the consensus. I mean some consensus is helpful in general, but I wonder why this way.
