Carpentry is an ancient profession, and still respected to this day. Though modern carpentry is a complex profession akin to engineering, it is colloquially viewed as simple enough for laymen to understand its concepts and tools.
Additionally, carpentry as a hobby is relatively popular both for its practicality and its relatively low bar of entry, with much room to develop and expand.
I personally like to find parallels between trades and crafts to help connect my thoughts and experiences to the more abstract world of software. I started my life in carpentry and joinery so it seems to be where my mind finds it’s foundations when thinking in systems and patterns.
