Programming Languages
for AI, not humans

What changes when the machine is the primary author — and what an AI-first language has to look like for the code to be cheap to debug, replay, and fix.

You just heard how teams put AI coding into the daily workflow. Now look at what the AI is writing… in.

The AI Coding Revolution

90%

AI-written code predicted

Dario Amodei, Mar 2025

30-50%

AI-written code at Big Tech

Google & Microsoft, 2025–26

100%

Some engineers today

Boris Cherny, 2026

Dario Amodei

Confirmed 90% prediction — "I don't write any code anymore." (Mar 2026)

Boris Cherny

Ships 10–30 PRs/day, zero manual code. Created Claude Code. (Feb 2026)

Andrej Karpathy

Coined "vibe coding," now full agentic — hasn't typed code since Dec 2025.

Jensen Huang

"The programming language is human. Everybody knows human." (Jun 2025)

The question is no longer whether AI will write code.
It's what humans will do when it does.

What the Builders Say

Independent voices — no AI products to sell

LT

"The python visualizer has been basically written by vibe-coding. Is this much better than I could do by hand? Sure is."

Linus Torvalds shifted

Creator of Linux & Git · Jan 2026

DH

"You can't let the slop and cringe deny you the wonder of AI. This is the most exciting thing we've made computers do since we connected them to the internet."

DHH shifted

Creator of Ruby on Rails · Jan 2026

KB

"90% of my skills dropped to $0. The leverage for the remaining 10% went up 1000x. I need to recalibrate."

Kent Beck evolved

Creator of TDD & Extreme Programming · 2023–2026

DS

"AI slop is a Denial-of-Service attack on open source maintainers." Shut down curl's bug bounty over AI-generated fake reports — but acknowledges AI finds deep bugs no tool ever could.

Daniel Stenberg nuanced

Creator of curl · FOSDEM Feb 2026

JC

"'Coding' was never the source of value. Problem solving is the core skill. AI training on open source code magnifies the value of the gift."

John Carmack

Creator of Doom & Quake · Mar 2026

SW

"Our job is not to type code into a computer. Our job is to deliver systems that solve problems." Coined "Deep Blue" for the existential dread developers feel.

Co-creator of Django · Feb 2026

If AI Writes All the Code… Does Language Matter?

LoCoBench: 8,000 scenarios, 10 languages, 12 models, 10K–1M token contexts

LoCoBench: LLM performance across programming languages

Two forces

Training data bias favours popular languages (Python, PHP). But the consistent ordering across all 12 models reveals systematic structural challenges too — it's not just familiarity.

TS < JS

TypeScript scores lower than JavaScript despite having types. Types alone don't help if they add complexity.

C, Rust: worst

Systems languages score lowest across every model. Headers, manual memory, macros — implicit complexity that no amount of training data overcomes.
