Why Software Code Can Keep Getting Worse
This essay argues that metaphors like a “sinking ship” are misleading for software systems because code does not have a natural floor where decline stops. Instead, software can accumulate endless layers of complexity, indirection, and performance loss, while organizations often struggle to simplify legacy systems due to knowledge loss, coordination costs, and incentives. The article uses a legacy order-processing system as an example of how technical debt can persist and expand over time.

Fragments: August 18
Martin Fowler reflects on Thoughtworks' focus on technical excellence and highlights Rachel Laycock's new writing series, Rachel's Ramblings. He also points to XConf Europe in London and discusses ideas about AI's strengths, including faster replication, pattern recognition, and understanding complex human and system behavior. The post closes with a note that many people still struggle to understand the role of data in software and organizations.
