Why Top Software Veterans Are Switching to Go and Rust in the AI Era
In the AI‑driven era, legendary programmers Eric S. Raymond and Uncle Bob argue that hand‑coding is fading, proposing two new criteria—AI’s ability to generate quality code and human readability—that make Go’s simplicity and Rust’s safety the preferred languages over traditional C, Java, and Python.
New language selection criteria in the AI‑assisted era
The traditional criteria—elegant syntax, rich ecosystem, comprehensive frameworks—were based on human hand‑coding efficiency. With AI agents generating most code, the criteria shift to two questions:
Can the AI assistant generate high‑quality code in the language?
Can a human reviewer understand the generated code at a glance?
“The age of hand‑coding is mostly over. The real standard now is whether the AI can generate the language well and whether I can read the generated code.”
Why Go and Rust?
Bob’s experience with Go : He chose Go for a new course not because of popularity but because it is fast and its syntax is straightforward. Students can focus on performance rather than language quirks. The ubiquitous if err != nil pattern is instantly readable, making AI‑generated Go code easy to audit.
“In the past I would pick Java, C# or JavaScript for a course. This time I chose Go because it’s fast. My students won’t waste time on Go’s syntax details; they’ll see Go’s performance.”
ESR’s view on Go vs. Rust : Go’s minimal surface area reduces token‑prediction ambiguity for AI, giving it a slight edge over Rust in code generation performance. Rust is positioned as the “ultimate landing pad” for code that requires strong memory‑safety guarantees after the exploratory phase.
“My AI friend generates both languages well, but Go’s code performs slightly better, possibly because of its smaller surface.”
“Rust meets my needs—writing it is hard, but reading it is fine.”
Critique of traditional “big‑factory” languages
ESR denounces Python’s historical chaos (Python 2→3 transition, GIL‑induced concurrency issues, package‑manager fragmentation) and argues that languages that accumulate complex features (C++, Java) become burdensome for AI because they increase cognitive load during review.
“Python was my favorite, but after the Python 2→3 disaster, GIL‑induced concurrency hell, and package‑manager mess, I now just go straight to Go.”
“Go code’s quality largely stems from the language’s tendency toward high quality, so AI‑generated Go code naturally inherits that.”
Shift from “Writer” to “Reader & Reviewer”
The discussion concludes that as code generation ceases to be the bottleneck, software engineers’ core value moves from writing code to auditing it. Three emerging priorities are identified:
Auditability > everything : Concise, easily debuggable code is essential; Go’s transparency provides strong security guarantees.
Safety foundation moves to Rust : Rust’s strict compiler guarantees memory safety, making it the reliable “digital infrastructure steel” for production code.
Embrace machine‑friendly “boring” tech : Languages that are simple for AI and reviewers—lacking syntactic sugar and hidden magic—are preferred.
