Functionality is an Asset
Software is a liability
Kevlin Henney is a strong proponent of the idea that less is more when it comes to software, especially with regards to functionality. This is a divergence from the customary idea that more functionality will require more software. There is a certain degree of logic to that idea, but it tends to miss that most software is not currently written with efficiency in mind.
Fixes and adding functionality tends to take the shape of patches and sloppily organized lines of code. This makes maintenance and upkeep of the code more difficult, and the code more likely to have gaps and breaks. This is what is meant by software as a liability.
By constantly refining our code and processes to be reused in as many places as necessary, TRELLIS is able to get advanced functionality and much faster bug fixes by using as few lines of code as possible.
