> This is where software goes wrong the most for me. I want, year after year, to come back to a tool and be able to apply the knowledge I acquired the last time I used it, to new things I learn, and build on it. I want to hone my craft by growing a deep understanding of the tools I use. This resonates with me deeply. Mastery of any subject needs a level of stability and permanence so that a skill base and a knowledge base doesn't erode away over time. Change is that erosive force, and we're so bad at knowing what changes to make in the software world.
