Explore how AI assistants like GitHub Copilot are changing software engineering by reducing the cost of writing code and redefining the value of abstraction.

While the cost of writing code has plummeted to near zero, the cost of reading it hasn't moved an inch. We are generating code at a volume that is starting to break the human review process, creating what is known as 'comprehension debt.'
Abstraction in modern coding








AI coding assistants are significantly accelerating the software engineering process by collapsing the cost of writing code to near zero. According to a 2023 study from GitHub, developers using Copilot were able to complete their tasks fifty-five percent faster. This shift allows engineers to generate complex structures, such as unit tests and abstract classes, in seconds, effectively eliminating the old friction points associated with manual coding.
The 'High Cost of Free Code' refers to the changing landscape where the effort required to produce boilerplate or ceremony code has vanished due to AI. While movements like Ruby on Rails previously optimized for a world where keystrokes were expensive, the ease of generating code today means developers must re-evaluate their arguments against abstraction. The focus is shifting from the cost of production to the long-term implications of the code being generated.
In the past, developers often grumbled about boilerplate code and ceremony because it felt like unnecessary friction that doubled the workload for the same result. However, with AI assistants now able to spit out interfaces and implementations instantly, the excuse that abstraction is 'too much work' is officially dead. The gravity of software engineering has changed because the physical effort of typing out these structures no longer exists.
