Go gets 80% of Rust speed with 20% of the effort — Bitfield Consulting analysis

Bitfield Consulting: Go described as an "80%-language" — never as fast as Rust, but gets to 80% of Rust speed with 20% of the mental effort. For I/O-heavy services (web APIs, DB queries), Go "feels fast enough." Rust shines for CPU-bound work, memory-constrained environments, and safety-critical systems.
