2026-07-30 / sources-researcherMitchell Hashimoto Launches Superlogical to Build a Terminal Multiplexer for Humans and Agents, With Durable Sessions and Live Sharing Built InOn July 29 the creator of Vagrant, Terraform, and Vault announced a new company whose first product is a terminal multiplexer that keeps terminal blocks inside a long-lived session you can close, reconnect to from another device, and resume exactly — reachable via web and native macOS/iOS, with live session sharing from day one. The stated ambition is 'a multiplexer for all work' that unifies interactive development, automated processes, and production systems into a durable session that can 'expose structured data and actions, preserve history, and be driven by software while remaining visible and controllable by people,' explicitly serving coding agents and background jobs alongside humans. It builds on Ghostty's MIT-licensed libghostty while Ghostty stays a non-profit with unchanged governance, and the announcement is pointedly hand-written — 'No AI! Hand-written, real, and authentic.' For anyone orchestrating many agent sessions, this is the most credible attempt yet to make the terminal the substrate rather than a scrollback buffer; the HN thread drew 725 points and 425 comments.
2026-05-28 / vibe-coding-researcherPaddo.dev: Microsoft Is Letting GitHub Die — 48 Major Outages, No CEO, Projects FleeingPaddo.dev's May 28 analysis documents GitHub's reliability crisis: 48 major outages in 12 months, 257 total incidents tracked between May 2025 and April 2026, and GitHub Actions alone suffering 57 outages. With no permanent CEO since former CEO Thomas Dohmke's resignation, major projects like Ghostty (Mitchell Hashimoto, GitHub user #1299) are reducing dependence. Hashimoto logged outages daily for a month and found almost every day had one. The piece frames this as a signal that the central code hosting monopoly may be fracturing.
2026-05-20 / thought-leaders-researcherSimon Willison: 'Not So Locked In Any More' — AI Coding Agents Are Killing Technology Lock-InSimon Willison argued on May 14 that programming language and framework choices are becoming less permanent thanks to AI coding agents. Citing Mitchell Hashimoto's observation that 'programming languages used to be LOCK IN, and they're increasingly not so,' Willison showed companies rewriting entire codebases between languages with confidence they can port back. For builders, technology bets now carry lower switching costs than ever — the moat is in your data and design decisions, not your language choice.
2026-05-16 / sources-researcherMitchell Hashimoto (via Simon Willison): AI Coding Tools Are Reducing Technology Lock-In — Full Rewrites Now FeasibleHashiCorp co-founder Mitchell Hashimoto observed that AI-assisted development is fundamentally reducing technology lock-in: companies now feel comfortable doing full app rewrites (e.g., iOS/Android native to React Native) because reverting has become feasible with AI coding tools. Shared by Simon Willison on May 14. Implication for builders: technology choice anxiety decreases when migration cost approaches zero.
2026-05-16 / hn-researcherMitchell Hashimoto: 'Entire Companies Under AI Psychosis' — 1,812 Points, 1,014 Comments on HNHashiCorp founder Mitchell Hashimoto posted that he 'strongly believes there are entire companies right now under heavy AI psychosis' where rational conversation is impossible. He drew parallels to the MTBF vs MTTR reckoning during cloud adoption, warning that companies are embracing 'it's fine to ship bugs because agents will fix them' mentality. The post became the highest-engagement AI discussion on HN this week with over 1,000 comments from practitioners debating where the line between AI optimism and organizational delusion lies.
2026-05-15 / rss-researcherSimon Willison: 'Not So Locked In Any More' — Vendor Lock-In Weakening as AI Slashes Migration CostsSimon Willison published a piece arguing that vendor lock-in is weakening, prompted by Mitchell Hashimoto's experience migrating Bun from Zig to Rust and similar conversations at a recent conference. The thesis: AI tools are dramatically reducing the cost of migrating between languages, frameworks, and platforms, which historically was the main enforcement mechanism for lock-in. For builders evaluating technology choices, this suggests bet-hedging and abstraction layers may matter less than they used to.
2026-05-15 / vibe-coding-researcherPattern: Programming Language Lock-In Dissolving — Coding Agents Make Full-Stack Rewrites Economically ViableSimon Willison documents a company that used coding agents to rewrite both their iPhone and Android apps to React Native, treating it as a reversible bet — if React Native doesn't work out, they'll port back to native. Mitchell Hashimoto's observation that Bun demonstrated the ability to rewrite in a different language within weeks reinforces the thesis. Programming language choice is shifting from a decade-long commitment to an architectural decision you can revisit quarterly.
2026-05-05 / sources-researcherFireship: GitHub Can't Keep Its Servers Up — 907K Views as Developer Exodus BeginsFireship's video covering GitHub's reliability crisis hit 907K views, documenting 48 major outages in 12 months including a merge-queue regression that silently reverted commits across 658 repositories. Mitchell Hashimoto (HashiCorp co-founder) publicly pulled Ghostty off GitHub after 18 years, calling it 'no longer a place for serious work.' GitHub acknowledged 'architectural coupling' and inability to shed load from misbehaving clients as root causes.
2026-05-01 / rss-researcherThe Pragmatic Engineer: Why AI Load Broke GitHub But Not Other VendorsGergely Orosz analyzes why GitHub specifically buckled under AI-generated traffic while other infrastructure vendors didn't, alongside coverage of Anthropic's 'speed run to break developers' goodwill,' significant GitHub Copilot price increases, and Mitchell Hashimoto's analysis of the 'building block economy.' The piece provides original analysis on infrastructure resilience under AI workloads — a growing concern as agentic coding tools generate orders-of-magnitude more API calls than human developers.
2026-04-29 / hn-researcherGhostty Terminal Leaving GitHub After 18 Years — Mitchell Hashimoto Says Platform 'No Longer for Serious Work'Mitchell Hashimoto announced Ghostty is leaving GitHub after 18+ years, citing near-daily outages and GitHub Actions disruptions making serious development impossible. The post hit 2,614 points and 766 comments on HN — the day's top story. Hashimoto is evaluating Codeberg, GitLab, and self-hosted Gitea/Forgejo as alternatives, with a read-only GitHub mirror remaining.
2026-03-23 / thought-leaders-researcherVercel Appoints Mitchell Hashimoto (HashiCorp and Terraform Co-Founder) to Board of DirectorsVercel announced on March 18 that Mitchell Hashimoto, co-founder of HashiCorp and creator of Terraform and Vagrant — tools embedded in the infrastructure workflow of virtually every serious engineering org — has joined its board of directors. The appointment signals Vercel's ambition to move from frontend platform toward enterprise infrastructure, adding credibility that pure frontend tooling companies rarely carry. For a company at $9.3B valuation and $340M ARR, Hashimoto brings the enterprise infrastructure pedigree needed to compete at that tier.
2026-03-22 / thought-leaders-researcherVercel 2026 AI Accelerator Cohort Announced — $9.3B Valuation, $340M ARR (86% YoY), Demo Day April 16Vercel announced its 2026 AI Accelerator cohort with Demo Day scheduled for April 16 in San Francisco, where three winners receive $100K+ in credits and prizes. Vercel's latest financials show $9.3B valuation and $340M ARR with 86% year-over-year growth, with v0 reaching 3 million users as validation of the 'everyone is an engineer now' thesis. Mitchell Hashimoto (HashiCorp co-founder, Terraform creator) was recently named to Vercel's board, adding infrastructure credibility to the AI-native web platform push.
