The abstractions in SICP need a revisit
The article discusses the limitations of classical computer science abstractions in the context of modern microarchitectures. It highlights how pointer chasing and environment retention create inefficiencies in contemporary hardware systems. The author argues for a reevaluation of these abstractions to better align with the physical constraints of current technology.
- ▪Classical computer science abstractions struggle under the thermal and spatial constraints of 2026 microarchitectures.
- ▪Pointer chasing creates dependencies that hinder memory-level parallelism, leading to significant performance penalties.
- ▪Serverless platforms face challenges with state retention that exacerbate the inefficiencies of pointer chasing.

SICP: An Architectural Trace of Pointer Chasing and Environment Retention on Modern SiliconWhy the elegant abstractions of classical computer science fail under the thermal and spatial constraints of 2026 microarchitectures.Nitin KholaMay 21, 2026ShareStructure and Interpretation of Computer Programs teaches that computer science is a branch of mathematical logic. It builds processes in an idealized sandbox where memory is infinite, pointer dereferences are instantaneous, and execution frames carry zero cost.Nevertheless, in the systems of 2026, hardware is not a mathematical plane. It is a thermal and spatial grid. The elegant abstractions of classical computer science run directly into microarchitectural bottlenecks.
