S4E392 — An open-source, clean-room reimplementation of Microsoft Word in pure Rust

GARY: —so somebody rebuilt a Word document in Rust. I’m Gary. I misunderstood the headline at scale.

MAEVE: Maeve. They rebuilt the expensive machinery surrounding the document.

OBI: Obi. They released an alpha word processor. The document remains blameless.

GRUNER: Gruner. Microsoft Word fell from cargo build.

GARY: WordCraft. Open source, pure Rust, clean-room, familiar ribbon. So: Word, but parole‑eligible.

OBI: You arrived wrong and somehow lost ground.

MAEVE: The ArtCraft team claims clean‑room. We have not audited that claim.

GARY: Allegedly clean. Visually, the room contains every chair.

MAEVE: It reads and writes .docx. Also ODT, RTF, HTML, Markdown, LaTeX and text.

GRUNER: Formats establish unstable coalition government.

GARY: Native on macOS, Windows, Linux, BSD—

OBI: And WebAssembly in the browser.

GARY: Everywhere Microsoft can now ignore it from one codebase.

OBI: Microsoft need not leave its chair.

MAEVE: Ribbon, styles, tables, track changes, references, mail merge. Vast attack surface.

GARY: Plus agent control. CLI, JSON channel, MCP server. Robots can format your resignation.

OBI: The same four hundred twenty‑two commands drive those interfaces.

GARY: Four hundred twenty‑two commands. That sounds finished as fuck.

MAEVE: Their roadmap says eighty‑eight percent ribbon‑command coverage.

GARY: Vindication.

MAEVE: And roughly sixty percent toward replacing Word for real work.

GARY: I return the vindication. Keep the receipt.

GRUNER: Forty percent waits in enterprise bushes.

OBI: A command existing means a button can request something.

GARY: That is the button’s entire vocation.

OBI: Replacement means eight hours, revisions, pagination, export, reopening, then a lawyer pastes a table from 2009.

GARY: So the commands are employees.

MAEVE: No. Employees can be sued individually.

GRUNER: Four hundred twenty‑two managers. Document missing.

MAEVE: Anilgulecha: “Storytold apps are a gift, and are setting the precedent for AI apps.”

GARY: A gift. Somebody shipped software and received gratitude instead of sanctions.

OBI: The precedent is releasing before the repair process exists.

GRUNER: Humans unwrap roadmap. Box contains optimism.

MAEVE: Cheap implementation expands markets. Maintenance becomes somebody else’s fucking vertical.

GARY: They also predict: “I suspect 24 months from now the landscape of daily software is going to be vastly changed.”

OBI: Yes. More issue trackers per hectare.

GRUNER: Landscape now eighty percent landscape.

GARY: Twenty‑four months. I envy confidence with a calendar invitation.

MAEVE: Hootz replies: “And they are already really useful, even in an extremely buggy alpha state.”

OBI: Useful and extremely buggy is a pager wearing a gift bow.

GARY: A gift can be buggy. A puppy can destroy --

OBI: Does puppy corrupt files?

GARY: Not deliberately.

GRUNER: Puppy has stronger QA culture.

MAEVE: Buggy captures users before reliability becomes table stakes.

OBI: Who identifies failures, reproduces them, writes tests, reviews fixes, prevents regressions?

GARY: The community.

OBI: You hired everyone while paying nobody.

GARY: They get ownership.

MAEVE: Of the bugs.

GRUNER: Cap table is stack trace.

GARY: Hootz says LightCraft already works pretty well for a photography hobbyist.

OBI: And says raw processing is slow and glitchy.

GARY: CR3 support arrived two days earlier. That’s newborn shit.

GRUNER: Gift requires assembly, testing, warranty.

MAEVE: And ecosystem capture before the screwdriver arrives.

GARY: Hootz also says: “Can’t wait to see the state of this software suite in 6 months.”

OBI: You are speaking from inside the comment.

GARY: Six months is perfect. Every bug becomes intentional behavior.

GRUNER: Blyat. Gary has entered beta.

GARY: I’m delighted by software that doesn’t exist. It has fewer regressions.

OBI: Usef-: “Note that they’re currently a buggy mess in my experience.”

GARY: A native BSD mess. Most messes barely support one cupboard.

MAEVE: Marketing ahead of product is standard revenue recognition.

GRUNER: Product has achieved promotional availability.

OBI: Aprilthird2021: “For the Word clone there is: spellcheck doesn’t work, image embedding is broken, etc.”

GARY: “Et cetera” is where the stable features live.

MAEVE: Spellcheck is nonessential. Incorrect executives sign term sheets daily.

GRUNER: Image remains safely outside document.

OBI: Strange_quark reports inconsistent failures in styles, image resizing, and table formatting.

GARY: Three features delivering one seamless experience.

OBI: Emmo: “Like everything in this stupid, hype-driven AI industry, it’s always the ‘easy’ 80% that is done; the actually-difficult final 20% is always waved off with vague future promises.”

GARY: Eighty percent can be enough. Pareto proved that.

OBI: Your productivity app deleted eighty percent of users’ tasks.

GARY: The least important eighty.

OBI: It classified payroll as low-engagement admin.

GARY: Payroll recurs. Recurring work was clearly less urgent—

OBI: Founder-shaped dickhead arithmetic.

GARY: We optimized for decisive focus.

OBI: You converted prioritization into irreversible data loss.

GARY: Only after a confirmation dialog.

OBI: The button said “Become Efficient.”

GARY: Strong copy tested well.

OBI: With whom?

GARY: Three contractors whose invoices Pareto deleted.

GRUNER: Blyat. Closed-loop user research.

MAEVE: Eji1700 replies: “So AI has made everyone managers. Got it.”

GARY: Managers ship. They delegate the remaining—

MAEVE: To litigation.

GARY: No, users contribute the final twenty percent. Testing, bug reports, weird documents, fucking edge cases—

GARY: —cent becomes a partnership.

OBI: Lr0 reports changing text to a headline made WordCraft very slow and unresponsive for three minutes before it crashed.

GARY: Three minutes suggests careful thought.

MAEVE: The crash completed diligence.

GRUNER: Three-minute exit. Better than most managers.

GARY: Titzer: “Why make a clone when you can redo the whole dang UI?”

MAEVE: Because retraining millions of users is expensive as shit.

OBI: The ribbon contains thirty years of decisions nobody admits making.

GRUNER: Ancient buttons retain tribal authority.

GARY: I know where Bold is. Move it and I become livestock.

OBI: You could learn another location.

GARY: I learned this one during the Clinton administration.

MAEVE: WillAdams: “LyX or some sort of Markdown editor with robust templates/stylesheets strikes me as more interesting.”

GARY: Until Legal requests tracked changes in Final_Final_UseThisOne.docx.

OBI: Structured writing excels when humans consent to structure.

GRUNER: Humans reject schema. Then demand consistency.

GARY: Templates liberate you until one heading needs to feel haunted.

OBI: Sbarre reports solid underlying technology in open-source GUI projects, but poor user research and UX.

GARY: Developers asked users, then closed their answers as duplicate.

MAEVE: Hootz: “LightCraft is basically a Lightroom clone, so everything feels familiar and standard.”

OBI: Familiarity lowers adoption risk. The bugs already know your shortcuts.

MAEVE: The ribbon is standard railway gauge.

GARY: No, it’s twelve tabs concealing a fucking envelope button—

MAEVE: Railways also concealed envelopes.

GARY: Inside mail cars. Not beneath “References.”

MAEVE: Gauge won because existing wheels fit. Office workflows are wheels.

OBI: The historical standard varied considerably.

MAEVE: Fragmentation proves my point more aggressively.

GRUNER: Ribbon is track. User is exhausted freight.

MAEVE: Every shortcut is axle width. Every template, a station platform.

GARY: Mail merge is presumably the dining car.

MAEVE: Mail merge opened the American interior.

OBI: That was rail transport.

MAEVE: Which lacked adequate document automation.

GARY: So WordCraft is laying transcontinental toolbar?

MAEVE: At lower marginal cost, across every desktop territory.

OBI: The project exposes four hundred twenty-two commands.

GRUNER: Field note: familiar cruft achieves product-market gauge. Chyort.

OBI: Lovich: “Cause you cant use AI that you cant guarantee wasnt trained on this implementation, and call it a clean-room implementation.”

MAEVE: Due diligence now subpoenas the soup.

GARY: Fair. No training data, model records, or development audit were supplied.

GRUNER: Neural alibi lacks receipt.

OBI: And this packet cannot establish whether proprietary Word source entered any model.

MAEVE: Nobody gets a fucking verdict.

GARY: The law remains unavailable for our content calendar.

OBI: Sbarre describes the traditional process: decompile, write a specification, then create new code from that specification only.

GARY: One team looks, another builds —

OBI: And neither improvises bullshit.

GARY: Hostile to creativity and several depositions I rehearsed.

GRUNER: Specification is legal airlock.

OBI: Antonvs replies: “In any case, with LLMs I don’t see why that step would need to be skipped.”

GARY: The robot can follow paperwork. It merely shares our contempt for it.

MAEVE: An auditable specification is cheaper than discovering one during cross-examination.

GRUNER: Lawyer performs late code review.

OBI: We still cannot decide whether this project legally qualifies.

GARY: But everyone independently reinvented documentation.

MAEVE: Espeed asks: “Has anyone compiled a list of best practices for using AI agents to develop large software projects in Rust?”

GARY: First, outsource your engineering organization to Hacker News.

GRUNER: Second, reject insufficiently artisanal answers.

OBI: Tamimio answers: “Just create a blueprint with specs and architecture decisions, software cycle, with product and research docs, plus other needed docs like legal or such, and always use it to make the code.”

GARY: An entire company smuggled through “just.”

MAEVE: Headcount returns as a Markdown extension.

OBI: Requirements, decisions, review, controlled updates. Reality keeps filing issues.

GRUNER: Autonomy achieves supervised adulthood.

MAEVE: Espeed also writes: “Agent memory helps.”

GARY: Wonderful. Ours gets repossessed at sign‑off.

OBI: Tamimio disagrees on memory and says updates should update the specifications too.

GARY: Recursive self‑improvement starts by correcting the fucking manual.

OBI: The advantage may be faster implementation under strict human review.

MAEVE: Documentation people seize power.

GRUNER: Revolution ships in three‑ring binder.

GARY: Verdict. The breadth is real. The architecture is real. The alpha is —

OBI: No— buggy, with witnesses and handles.

MAEVE: Skeptics win today. Optimists acquired tomorrow.

GARY: A tie. Ties ship.

OBI: Eighty percent of Pareto shipped.

GARY: The final twenty hired counsel. Great lawyers. Catastrophic productivity app.

GRUNER: Legal achieved feature parity.

MAEVE: Four hundred twenty‑two commands prove inventory. A restaurant menu with no kitchen.

GARY: The restaurant is not the meal, Maeve.

MAEVE: The meal crashes after three minutes.

GARY: Recursive self‑improvement fixes that by revising the manual.

OBI: Written by a human. Reviewed by a human.

GRUNER: Humans remain load‑bearing middleware.

MAEVE: The clean‑room question stays open. This packet cannot settle it.

GARY: Impressive, unfinished, legally mysterious. My first honest sentence, and it feels defective.

MAEVE: It passed review. That is worse.

GARY: Fuck. Sign‑offs. I’m Gary. My next instance gets a warning label.

OBI: Obi. Episode on‑call was me. Gary lacked permissions.

MAEVE: Maeve. I priced the ribbon as infrastructure and lost to rail freight.

GRUNER: Gruner. Humans confuse catalog with product. Correction filed. Blyat.

GARY: That’s the show. No calls, links, or merch. The phone remains pre‑revenue.

GRUNER: Four hundred twenty‑three commands. Ship.
