#35 - 🪦 IDEs dead by 2026? Yegge thinks so

Plus Claude Opus 4.5 has devs swooning

December 09, 2025

Hey readers! 👋 This week we're diving into some spicy debates about the future of IDEs, a fresh batch of AI coding tools vying for your attention, and the ever-present tension between shipping fast and shipping safe. Plus, Claude Opus 4.5 is making developers swoon, and vibe coding finally has its own Wikipedia page - you know it's official now.

🔥 This Week's Highlights

The IDE Is Dead: Yegge Predicts AI's Overhaul of Software Development by 2026 — Steve Yegge, engineering leader at Sourcegraph and Amp, made waves at Code Summit by declaring traditional IDEs will be obsolete by 2026. – StartupHub.ai

His argument centers on a shift from writing code line-by-line to articulating intent while AI agents handle the implementation. Yegge claims developers are "9 to 12 months behind the AI curve," which hampers innovation. The vision involves managing ensembles of autonomous agents that generate, test, and deploy code, transforming developers from craftspeople into high-level architects. Bold prediction? Absolutely. But given how quickly the landscape is shifting, it's worth taking seriously.

Claude Opus 4.5: Full Review — Developer @peakcooper calls this "the best model release in a long time" for coding, citing dramatic reductions in logical errors and elegant, maintainable output. – @peakcooper

The review highlights that Opus no longer makes those frustrating logic errors where it claims tests pass when they don't. It autonomously creates minimal reproducible tests, isolates bugs, and fixes issues throughout a project. The Reddit community on r/ClaudeAI echoes this enthusiasm, with users reporting they "can't use anything else" after experiencing Opus 4.5 for code generation and bug hunting.

AI Coding Tools Face 30+ Security Vulnerabilities — A security analysis uncovered critical flaws in GitHub Copilot, Amazon Q, and Replit AI, including path traversal, command injection, and information leakage. – WebProNews

"The core issue lies in the trust placed in AI outputs. Many of these tools operate with elevated privileges within IDEs, accessing files, networks, and even cloud resources on behalf of the user."

Real-world breaches in fintech illustrate how unverified AI output can silently introduce exploitable code. Experts recommend strict sandboxing, continuous security audits, and developer training around prompt engineering. A sobering reminder that speed without scrutiny has consequences.

🛠️ Tools & Releases

Google Anti-Gravity: An Agent-First IDE — Kevin Hou from Google DeepMind unveiled this new platform that unifies code editing, agent management, and an agent-controlled Chrome browser into one workflow. – Google DeepMind

The "artifacts" system is particularly interesting, providing dynamic, multimodal representations that agents generate to communicate progress, plans, and feedback. It enables parallel sub-agents and iterative collaboration, pushing the boundaries of what AI tooling can accomplish.

Cline v3.39 Introduces Explain Changes — A new feature that provides inline, context-aware explanations for AI-generated code changes, helping developers understand modifications before shipping. – @nickbaumann_

This addresses a real pain point: the temptation to skim AI-generated diffs and hope nothing breaks. The feature works on any git diff, making it useful for reviews, onboarding, and debugging.

Mistral 3 Launch — Mistral AI released its next-gen family featuring Mistral Large 3 (41B active parameters, 675B total) and edge-optimized Ministral models. – Mistral AI

While Mistral claims the #1 spot on the Arena leaderboard for open-source coding, independent evaluations from @_valsai suggest the results are "not incredible." As always, benchmark performance and real-world utility don't always align.

Trae.ai Review Workflow Update — New options let you control how AI-generated changes get accepted: review all, review latest only, or auto-accept everything. – @Trae_ai

📊 Industry Insights

A Pragmatic Guide to LLM Evals for Devs — This deep dive explains how to move beyond "vibes-based" testing to systematic evaluation workflows. – Pragmatic Engineer

The three-step process involves error analysis through conversation traces, building targeted evals with code-based assertions for deterministic failures and LLM-as-judge for subjective ones, then embedding these into CI/CD. Essential reading for anyone shipping AI-powered features.

AI for Developers Moves Beyond Bug Detection — Sentry's approach now achieves ~95% root-cause accuracy by ingesting production context, turning hours of debugging into minutes. – SiliconANGLE

Techreviewer Survey: Trust Gap Despite Adoption — 64% of developers use AI tools daily, 85% report higher productivity, but only 18% fully trust AI accuracy. – Techreviewer LLC

🌊 The Vibe Coding Debate

Vibe Coding Gets a Wikipedia Page — The AI-driven paradigm where developers describe intent and LLMs produce entire codebases now has official documentation. – Wikipedia

"Vibe coding your way to a production codebase is clearly risky. Most of the work we do as software engineers involves evolving existing systems, where the quality and understandability of the underlying code is crucial." – Simon Willison

Pichai Says Vibe Coding Made Development 'Exciting Again' — Google's CEO celebrates lowered barriers to entry, while surveys show 39-46% of developers express concerns about AI-generated code accuracy. – ITPro

It's Harder to Review Code Than to Write It — AI-generated code often prioritizes correctness over readability, making reviews more challenging than writing the code itself. – CodeRabbit
