The gut you can't code

A conversation with Claude (Opus 4.8) that began as a narrow question about why long AI sessions get expensive, and wandered somewhere I didn’t expect — through lossy cognition, the limits of introspection, and whether a machine could feel the frustration of not being able to read its own mind. Lightly edited; my prompts, its answers.

Marcelo — Why does LLM token cost grow quadratically as the session evolves?

Two different quadratics get conflated here, and the one that drives session cost isn’t the famous one.

GOOS/GOARCH combos on macOS

The following is a survey of GOOS/GOARCH support on my Mac, using src/go/build/syslist.go@7cbfa5 as the source of combinations to try. The following table shows combinations that built successfully (✅) and those that failed (❌). The rest, denoted by ‘—’, were reported by Go as unsupported combinations, e.g.:

$ GOOS=js GOARCH=386 go build
cmd/go: unsupported GOOS/GOARCH pair js/386

GOARCH → GOOS ↓	386	amd64	amd64-p32	arm	arm64	mips/le mips64/le ppc64/le s390x	riscv64	wasm
