AI takes over code authorship at major tech firms

AI takes over code authorship at major tech firms

New Capabilities

Google's CEO says three-quarters of new code is now machine-written.

April 24th, 2026: Pichai announces 75% at Cloud Next

Overview

For most of computing's history, every line of production code at a major software company was typed by a human. On April 24 at Google Cloud Next 2026, Google CEO Sundar Pichai said 75 percent of new code at the company is now generated by artificial intelligence and reviewed by engineers. That share was 25 percent in October 2024.

The workforce consequences are now explicit. Days after Pichai's announcement, Meta said it would cut 8,000 jobs (10 percent of its staff), beginning May 20. An internal memo directly linked the cuts to AI infrastructure spending projected at $162–169 billion in 2026.

Microsoft simultaneously launched the first voluntary retirement program in its 51-year history, targeting roughly 7 percent of its U.S. workforce. It explicitly exempted AI, Azure OpenAI, and GitHub Copilot engineering teams. Both companies named AI automation as the enabling factor for cuts in software testing, content moderation, and certain engineering roles.

Why it matters

If most code at top firms is machine-written, the entry-level path into software engineering (the highest-paid mass profession in America) is being rewritten in real time.

Fictional AI pastiche — not real quote.

"The Prince who replaces his captains with siege engines need not fear their mutiny — yet he would do well to remember that engines do not garrison towns, nor do they govern the loyalty of those who remain."

  1. Pichai announces 75% at Cloud Next

    Latest Statement

    Pichai opens Google Cloud Next 2026 saying three-quarters of new code is AI-generated, alongside a $240B cloud backlog and 750M monthly Gemini users.

  2. Meta announces 8,000 layoffs, cites AI investment needs

    Labor

    Meta said it will cut approximately 8,000 employees — 10 percent of its workforce — starting May 20. The company's internal memo explicitly linked the reductions to freeing capital for its $162–169 billion 2026 AI infrastructure budget.

  3. Microsoft launches first-ever voluntary buyout program

    Labor

    Microsoft offered early-retirement packages to employees whose combined age and years of service reach 70, targeting roughly 7 percent of its U.S. workforce. AI, Azure OpenAI Service, and GitHub Copilot teams were explicitly exempt, concentrating reductions away from AI engineering.

  4. Anthropic and OpenAI engineers report ~100%

    Statement

    Senior engineers at the leading AI labs say they have stopped writing code by hand, delegating it almost entirely to in-house models.

  5. Google launches Antigravity and Gemini 3

    Product Launch

    Google releases an agent-first IDE bundled with Gemini 3 Pro, designed to orchestrate multiple autonomous coding agents.

  6. Google's share crosses 50%

    Statement

    Pichai updates the AI-generated code figure to about half of new code at the company.

  7. Microsoft puts a public number on it

    Statement

    At Meta's LlamaCon, Satya Nadella says 20 to 30 percent of Microsoft's repository code is now AI-written.

  8. Google's first 25% disclosure

    Statement

    Pichai tells investors that more than a quarter of new code at Google is being generated by AI assistants.

  9. GitHub launches Copilot

    Product Launch

    Microsoft's GitHub releases the first mainstream AI pair programmer, suggesting code completions inside the IDE.

Historical Context

3 moments from history that rhyme with this story — and how they unfolded.

April 1957

FORTRAN and the compiler revolution (1957)

IBM shipped FORTRAN, the first widely used high-level language, with John Backus's optimizing compiler. A routine that had taken 1,000 lines of assembly could now be written in roughly 50 lines of FORTRAN, cutting programming effort by a factor of five to ten.

Then

Programming stopped being 'hand-to-hand combat with the machine' and opened to scientists and engineers outside the small priesthood of assembly coders.

Now

Demand for programmers exploded rather than collapsed. Each productivity gain enabled software in domains that had been economically out of reach, and the profession grew tenfold over the following decades.

Why this matters now

The closest historical analogue: a tool that drastically cuts the per-line cost of code. The compiler precedent is why Pichai and others argue AI coding will expand engineering employment, not shrink it — though the transition reshaped which skills mattered.

1979 onward

Spreadsheets replace bookkeeping clerks (1979-1990s)

VisiCalc, then Lotus 1-2-3 and Excel, automated work that armies of bookkeepers and junior accountants had done by hand on green ledger paper. Economist James Bessen later documented that roughly 400,000 bookkeeping jobs disappeared while accounting and analyst roles grew by more than 600,000.

Then

The most routine, entry-level financial roles contracted sharply through the 1980s and 1990s.

Now

The profession reorganized upward: fewer pure data-entry jobs, more financial analysts and modelers doing work that wasn't feasible without spreadsheets.

Why this matters now

Spreadsheets did to bookkeeping what AI coding may do to junior software engineering — eliminate the routine production layer while expanding the analytical and design layer above it.

1811-1816

Power loom and the Luddite revolt (1811-1816)

Mechanized weaving displaced English handloom weavers, whose wages collapsed from around 21 shillings a week in 1797 to about 6 shillings by the 1830s. Organized weavers smashed machines across Yorkshire and Nottinghamshire; the British government deployed troops and made frame-breaking a capital offense in 1812.

Then

A generation of skilled weavers was destroyed economically, with widespread poverty and migration.

Now

Textile output and overall employment in the sector grew enormously, but the gains accrued to a different set of workers — factory operatives, not the displaced craftsmen.

Why this matters now

The cautionary parallel: aggregate productivity gains from automation do not automatically benefit the workers whose specific skills are being automated. Whether AI coding follows the compiler path or the power-loom path will depend on how quickly displaced engineers can move into the new orchestrator and reviewer roles.
