Could you build this?
No Writing 'the fastest JSON parser for Go' requires low-level performance engineering, custom SIMD vectorization (AVX2/NEON), assembly tuning, and zero-allocation memory models that cannot be achieved through vibe coding.
What it would actually take: High-performance JSON parsers (e.g., simdjson ports or sonic) are implemented using architecture-specific SIMD instructions (AVX-512, AVX2, ARM NEON) via Go assembly or native intrinsics to parse multi-byte structural characters in single CPU cycles. They use zero-allocation structural indexing (tape structures), custom branchless float/integer parsers, and unsafe pointer manipulation to bypass Go's boundary checks. This demands elite systems programmers with deep compiler, CPU microarchitecture, and memory layout optimization expertise.
