The 'Hidden' Costs of Great Abstractions
The article discusses the trade-offs of abstraction in computing, where simplifying complexity has enabled faster development but often at the cost of quality and deep understanding. As tools like LLMs lower the barrier to software creation, the distinction between functional and well-crafted code becomes harder to discern. The author, a once-passionate developer now unemployed, reflects on how these shifts have impacted both software quality and his personal livelihood.
- ▪Abstraction in computing has reduced the need for deep technical knowledge, leading to faster development but often lower-quality software.
- ▪With the rise of LLMs, even inexperienced users can generate functional code, though it may lack reliability or efficiency.
- ▪The author, formerly skilled in low-level systems and automation, has been unemployed since July 2025 despite extensive job-seeking efforts.
- ▪Historically, understanding machine-level details was crucial due to high costs of computation and errors.
- ▪Poor-quality abstractions can lead to software that is slow, buggy, and built on unreliable foundations, much like using substandard materials in construction.
Opening excerpt (first ~120 words) tap to expand
In the world of computing, we tend to abstract away complexity. Doing so seems liberating. It enables us to focus on the bigger picture. Unfortunately, in doing so, the fidelity of our understanding often decreases. We sometimes end up blinding ourselves. Historically, running computer programs was expensive and time consuming. Errors were far more costly than they are today. Knowing the intricacies of how the machine operated was essential. Otherwise, you wouldn't be able to get it to do much at all. Then the barrier of entry lowered. Memory and computation power grew. People ceased thinking about how to save a few bytes or CPU cycles. Many developers simply couldn't.
