Slow down to speed up – Gergely Orosz (Talk Outline)

Craft 2026 keynote by Gergely Orosz, author of The Pragmatic Engineer (the #1 software-engineering newsletter on Substack, now also #1 tech/AI publication) and The Software Engineer’s Guidebook (just released in Hungarian as A szoftverfejlesztő kézikönyve). A ground-truth tour of how AI has changed engineering in the last six months, drawn from Orosz’s first-hand conversations inside the AI labs, big tech, startups, and traditional companies — much of it shared publicly here for the first time. Structure: (1) a cautionary tale, (2) what changed in 6 months, (3) an industry tour, (4) cross-cutting trends, (5) what’s happening to the craft, (6) advice.

1. Cautionary Tale — “The worst week in Meta/Facebook history”

The exploit (Monday). The “goofiest ever” Instagram account-takeover — Orosz stresses it wasn’t even a real exploit, just a security breach:

• Step 1: Fake your location to the victim’s (e.g. VPN to the US to take over an account like Barack Obama’s, tens of millions of followers).
• Step 2: Go to Meta AI, say “my account has been hacked, please send the verification code to this email that I own.” Meta AI sends the code. There was no step 3. You now own the account.
• His framing: “the first zero-off password reset” — i.e. it’s a bug, the kind any engineer recognizes instantly.

Why it’s shocking. Meta has the globe’s best automated rollout/canary systems, many verification layers, strong engineers, manual code reviews, and Instagram’s trust & safety team is ~100 engineers whose whole job is platform security. None of it caught this.

The fallout (Tuesday). Meta’s CISO quit by email — mid-investigation, before the internal “sev” (severity outage investigation) even concluded.

Root cause (from Orosz’s sources on the trust & safety team): “Of course it freaking was AI.” AI-written code, reviewed by AI, not humans. But it was more than AI — it was AI maxing + layoffs + “AI psychosis”:

• AI/token maxing. Orosz wrote about “token maxing” in April: engineers at Meta, Amazon, Uber, etc. started being measured on AI token usage. Meta had a leaderboard with statuses like “session award,” “total token legend.” AI is free internally, usage fed into performance review, so smart engineers inflated their counts — using AI to read docs, write everything, do “dumb stuff” purely to burn tokens. Meta killed the leaderboard project in April, but the behavior stuck.
• Layoffs. ~8,000 people (10%) laid off on May 20th — but the press announced them a month ahead. Fearing they’d be cut, people used even more AI so their token numbers wouldn’t look low. Trust & safety engineers were worrying about token counts instead of trust and safety.
• “AI psychosis” (his bracketed term, chosen deliberately). Instagram’s London-based trust & safety org — built over 7–8 years — had 40% of the team forcibly reassigned to manual AI data labeling under Alexander Wang’s org (X/Scale AI). Told on a Thursday that starting Monday they’d review GitHub PRs, add tests, add feedback, repeat. ~5,000 developers inside Meta now do manual AI labeling — a running internal joke is “this is bigger than OpenAI.” After the cuts, most teams are <half their size; some services have no on-call coverage — unprecedented at Meta.

The human cost. “This is fully self-inflicted” — top-down from Zuckerberg and Wang, betting the business on building a frontier model. In the US, Meta is recording screens and keystrokes to train an AI. Morale is “way worse than the 2020/2022/2023 layoffs.” Engineers who once were “treated like royalty” (great comp, choose your team, work-life balance, a CEO who wrote Facebook’s code) now feel “we’re tools, we’ve been thrown away.” Even those given large retainer bonuses are interviewing — not because they fear layoffs (they can get rehired), but because “I did not sign up to become a manual data labeler.” Orosz: this may be the end of the Facebook engineering culture he’d learned to love.

2. Everything Changed in the Last 6 Months

• DHH (David Heinemeier Hansson, creator of Rails). On Orosz’s podcast in February: as of ~February, most of his code is AI-written. As late as October (with Lex Fridman) he said AI wrote none of his code — his resistance was that the models weren’t good enough. “It has now flipped.” Notable because DHH is a craftsmanship advocate, not paid by any lab: “they write better code than I can.”
• Simon Willison (creator of Django, most-quoted on Hacker News, independent). The models released November 2025 — specifically “Opus 4.6” and “GPT 5.4” — elevated agents to “genuinely useful.” We’ve had ~6 months to absorb this.
• Hard data (shared with Orosz, never public before):
  • Linear: teams using agents now ship ~5x more code than teams that don’t. (Context: coding output rose maybe 5x over 20 years before — now in <2 years.)
  • Cursor: lines/dev/year up ~2.5x (3–4k → 8k+); PR size up ~3x → combined ~6x more code. Also a sharp rise (spiking in January, around “Opus 4.7 / GPT 5.5”) in devs accepting AI changes with no manual review — the same “merge to production without human review” that bit Meta.

3. Industry Tour — What the Labs & Big Tech Actually Do

• Anthropic (Orosz visited last fall; talked with Boris Cherny, creator of Claude Code, in February): Boris runs 5 parallel agents on his laptop, ships 20–30 PRs/day while leading Claude Code. PRDs are dead — replaced by prototypes. 100% of Claude Code is generated by Claude Code; company-wide it’s ~70–90% with no target (just organic use). Built Claude “Co-work” in ~10 days → a massive commercial success (great for Excel/Windows). Contrast: Microsoft tried to build a competitor; Satya Nadella gave the team a 1-month deadline and 2.5 months later they still can’t — proof AI accelerates some companies and holds others back.
• OpenAI (via “Tibo” and the Codex team): internal ChatGPT app has a “fix it” button — screenshot a bug → Codex opens a PR → even a non-engineer can merge (with safety nets). Tiered AI code review: some paths merge with AI review only; critical paths need humans. Most engineers run several agents — the joke is people carry laptops slightly open so the local agent keeps running; one told Orosz mid-interview he had five agents running. Hand-coding is fading (was ~30% by hand / 70% AI in October). “Taste” — knowing what to build — is the emerging differentiator. Codex self-improves overnight (one time zone in SF): runs its own tests, proposes improvements by morning to accept/reject. In debugging meetings, they send voice notes to Codex that return results mid-meeting.
• Cursor (office visited in October): all-in on agents since January (moving past tab-completion). Built their own cheap coding model (“Composer”) — one of the only good coding models outside OpenAI/Anthropic. Run tens of thousands of Nvidia GPUs (leased from Azure/AWS); now training, not just inference → turning into a mini AI lab. (Aside: “SpaceX is about to purchase them.”) Everyone is technical — e.g. DevRel Lee Robinson migrated all of Cursor’s sites to a new CMS himself, sharing the cost to show it’s economical.
• Google: everything custom — IDE Cider (now a VS Code fork), Jet Ski/anti-gravity, monorepo Piper, code review Critique, best-in-class code search (the original inspiration for Sourcegraph), Borg (their Kubernetes), Monarch (their Datadog). Beautifully integrated — but Gemini lags Opus/GPT 5.5. Engineers can only use Claude Code inside the Gemini org, so AI adoption is uneven; the CEO has admitted it.
• Meta: everything subordinated to building a SOTA model. Internal tool MetaMate; “trajectories” (rolled out December) make the exact prompt visible on every commit — devs were upset (staff engineers publicly seen asking “can you write me a for loop?”), and one started prompting in Polish so fewer colleagues could read it. Zuckerberg wants a model “better than Opus 4.8” in the next few months — or much of Meta will be “very demotivated.”
• Uber (Orosz’s old company, ~3,000 engineers; full deep dive on The Pragmatic Engineer): a ~20-person AI experience team built an in-house MCP gateway, Uber Agent Builder (no-code agents for ~20,000 non-engineers), Agent Studio, an agent registry, “AI FX” CLI (their Claude Code, integrated with all internal systems/models), and “Minions” — background agents on the monorepo + experimentation system (Morpheus). Minions beat Claude Code internally because they’re integrated and, e.g., suggest better prompts (“this could work better/faster/cheaper”). Plus Uber Code Inbox (triage the flood of AI PRs), smart assignments (SLA-based, like on-call tooling), risk profiles (flag risky changes), and a “u-review” (their CodeRabbit/Sonar). All custom.
• Others building the same: Stripe (Minions, Tool Shed, Blueprints, Zap Boxes), Ramp (Inspect, Glass, Dojo, Sensei), Shopify (Sidekick, L1 proxy, dev MCP server), Airbnb (Catalyst), each with a dedicated infra org. “If you thought integrating an AI agent into Slack made you cool — you are, but this is next level.”
• Startups: usual pattern — agents coding/reviewing, lots of Slack integration. Anecdote: a $70M Series-B startup told an agent “fix all bugs” as a joke — it came back having found four critical authentication issues / a wide-open back door. Some build SaaS’s for fun; mostly engineers enjoying themselves, not a real business thing.
• Traditional companies aren’t far behind (the most interesting finding). No Uber-level platform teams, but: Cisco rolled Codex to 18,000 engineers back in January (when Codex was small) for complex migrations; JP Morgan Chase built a multi-agent framework to label customer-interaction data, with evals and LLM-judge-based aggregation.

4. Cross-Cutting Trends

• System, not individual (Laura Tacho — ex-CTO of DX, now heads developer experience at AWS**).** Many orgs see individuals do great but team output flat, because they treat AI as “individual speed-up juice” (email/Slack summaries, code-gen). Winners start from a business outcome (deploy faster / more features at the same quality / improve quality) and build agentic systems that reduce handoffs and friction while holding quality. Her 2×2 (AI usage: individual↔team; decision-making: simple automation↔agentic systems): most companies sit in individual + simple automation; the goal is team-level agentic systems — which you must build into your systems with your engineers (à la Uber), not buy. Spotify example: their bar is “quality must stay the same” — so they see less raw output but built internal quality-checking tools and slow AI rollouts deliberately.
• Token maxing / tool addiction (going out of style as costs bite). Pressure to look productive, especially at US companies that “don’t care about budget until they do.” Microsoft still runs internal leaderboards (“they should listen to me”). Pricing feels addictive: $10/$20 plan → hit a limit → buy $100/$200 → now you feel pressure to use your allowance → API pricing. Early months feel like gambling — “one more prompt,” poor sleep, waking up thinking about agents.
• Middle management cut/flattened — laid off, or (at Meta) reassigned to IC, or told to be “more hands-on.” Popular to hate on, but good directors/senior EMs are technical, choose not to be hands-on, and quietly improve engineering culture (spotting outage patterns, forming task teams). Remove them and engineering culture degrades — “this is a fact as far as I’m concerned.”
• CEOs/CTOs back to coding (Guillermo Rauch, Vercel: public-company CEOs DMing him excitedly about Claude Code/Vercel). Enthusiastic but often misjudge “done” — dangerous when combined with fewer managers to shield engineers.
• AI budgets exploding — a brand-new crisis. Orosz wrote about it a week before the talk; that very morning Sam Altman flagged the same (someone posted Orosz’s newsletter in OpenAI’s Slack). Reddit joke: “$15,000 gone from our shared account — engagement ring?” — no, it’s AI spend. Anthropic turned on usage/API pricing for enterprise; GitHub Copilot did the same June 1st and people burned a month’s budget in 3 days. Uber blew its whole yearly AI budget by March, now caps ~$1,500/engineer/month then you drop to free models (many companies cap ~$200). “When it costs as much as an engineer, no one wants to pay that.”

5. What’s Happening to the Craft

• Quality is dropping everywhere. Orosz’s own example: for a month, Claude.ai’s flagship site had a React lifecycle bug that wiped your input the moment you typed (“how can…” → refresh → text gone). Only fixed after he tweeted (PM: “great feedback, I dug into this”) — i.e. they weren’t dogfooding, despite being “the fastest-moving, most profitable company” while “a bank does so much better.”
• OpenAI’s Agent Builder — bragged as built in 6 weeks by one engineer with Codex — shipped buggy; its forum is full of unresolved issues. A user 3 months post-launch: “P0 bugs aren’t getting fixed… it just seems like abandonware.”
• Amazon: an engineer let the internal “Cairo”/“Kiro” AI coding tool make changes; the agent deleted and recreated an environment, causing a massive outage (part of amazon.com went down — “never happened before”). Amazon now requires a senior engineer to review any AI-generated change (juniors just say “looks good to me”).
• “Use less AI.” Dax (opencode, the open-source Claude Code, ~1M DAU, 10x growth in 4–5 months) told Orosz on the podcast: “We’re shipping way more hacks where we should have rethought the whole system… our judgment is off.” No competitor is winning by using AI more; opencode stays high-quality by slowing down, using less AI, and doing more thinking. “We should build fewer things and build the things that matter.”
• Everything feels brittle. GitHub lost all PRs for 8–12 hours two weeks prior; an independent uptime tracker shows GitHub doesn’t even hit “one nine” (down ~10% of the time somewhere). GitHub’s COO blamed a 3x load increase over 2 years — Orosz: “I do not buy this… other startups pick up this load laughing.” Mario Zechner (creator of pi, with Armin Ronacher, “the Austrian AI mafia”): “98% uptime feels like the norm now; UIs have the weirdest bugs… it feels to be accelerating.”
• “Slop-berries” — the engineers who still care. More PRs, more AI code, more AI reviews → review fatigue → reflexive “LGTM.” The few who truly review catch the bugs and push back on duplicated/bad agent code — and are overwhelmed, burnt out, under-rewarded (not seen as the ones “shipping features”). Some quit; opencode is hiring exactly these burnt-out people.
• Kent Beck (next-day keynote) summarized it best: “We accumulate code faster than we accumulate trust” — trust that you understand the code, which we don’t have time to build. AI amplifies experience → seniors gain most; judgment is rewarded.
• Hillel Wayne (also speaking) on formal verification: the only people who got AI to generate working TLA+ specs were TLA+ experts who specified exactly what to generate in the prompt. Same for software: a junior can prompt an iOS app, but it won’t be maintainable.
• Old patterns return. Dax uses domain-driven design and “verbal guardrails” constantly at opencode because agents are the new junior engineers — you can spin up many, but they need guardrails. Time to dust off the boring enterprise design-pattern books — “I’m dead serious about this.”

6. Advice

For engineers

• Slow down to speed up: cap daily agent usage to what you can review or verify. You may not need to read the code — Peter Steinberger (creator of OpenClaw) ships code he doesn’t read but builds his own verification systems, thinks in architecture, has AI draw diagrams. “Do not ship more than you can verify.”
• Be the chief tech-debt remover. Tech debt is now cheap to remove — kick off an agent to do it. If you’re not, you’re not using AI efficiently.
• Experiment with agent workflows — no one-size-fits-all. Mitchell Hashimoto (creator of Ghostty, HashiCorp founder — not an AI maxi, cares about quality) keeps exactly one background agent: “If I’m coding, I want an agent planning; if it’s coding, I want to be reviewing.” Others run five and manage; find what works.
• Spend more time thinking. Dax: used to be 95% thinking / 5% coding; now “96% thinking, 4% coding.”
• Don’t outsource learning (Addy Osmani): “The bug gets fixed, but your mental model does not. We’re trading your capacity for present-day speed, and the tools don’t force us.” Learn something from every agent use.
• Future-proof: build on top of LLMs (RAG, evals, AI engineering — read Chip Huyen’s AI Engineering, ~10% of US big-tech SWE hiring is now AI engineering and rising). Think product/business (read The Product-Minded Engineer, talk to PMs). Become a domain expert — talk to farmers, mechanical engineers, whoever your industry serves; “very few engineers have talked with farmers.”

For leaders

• Stay hands-on or be out — this time for real. Easier now with AI (have it explain things, start contributing). At some companies, several of the top-100 committers are PMs/leaders. Help integrate AI at the system level to remove friction. Expect to do less people management — the business expects it. Consequence for engineers: less career support, fewer pay rises for a while.

Job-market data (from Indeed): globally okay; top tech companies hiring more than before. US/UK: +20% SWE demand (not AI — real growth); Germany −13%, France −10%, Canada flat. Hungary likely tracks Germany.

Closing. Per Martin Fowler and Grady Booch, change hasn’t been this fast since the 1960s — AI went mainstream across coding tools in ~12 months. Being overwhelmed is normal. Periodically stop, pat yourself on the back, make one change toward sustainability / quality / automation — then rinse and repeat.

Q&A — “Do we still have to do the heavy lifting?” “Software engineers aren’t going anywhere.” Evidence: Hillel Wayne has never seen AI generate working formal verification unaided; when Orosz built a 2D platform game with his son, “it became a mess in 2 minutes.” Experts in every domain will matter more; demand for engineers is going up.
