Claude AI's Vibe Coding: The Engineer's New Workflow
The Vergecast on Claude's vibe coding, email safety, and phone upgrade timing
The latest Vergecast lands with a trio of questions that cut straight to the heart of modern tech anxiety: Can an AI actually write its own code, and do we trust it? How paranoid should you be about your inbox? And when is the right moment to finally ditch that three-year-old phone?
We start with Anthropic’s Boris Cherny, the head of Claude Code, who dropped a headline-grabbing claim: Claude now writes 100 percent of his code. He walks us through what that actually looks like, how his own relationship to the code has shifted, where vibe coding came from, and why anthropic is betting big on making Claude Code feel less like a tool and more like a coworker. Then we pivot to email safety (because that “check your inbox” feeling is rarely innocent) and the eternal upgrade dilemma.
Subscribers get the ad-free version, but everyone gets the substance.
Claude Code is a developer tool for developers.
Boris Cherny’s confession that Claude Code now writes every line of his code isn’t a flex. It’s a map of where we’re headed. If we’re going to trust code we didn’t write, we need to rethink everything: how we guard our inboxes, when we swap our hardware, and what we even mean by “building” software.
Vibe coding is the promise. Email safety is the discipline. Phone upgrade timing is the calculus.
The Vergecast this week laid all three on the table, not as separate problems, but as a single, evolving calculus for how we live with machines that keep getting smarter.

Common Questions Answered
What exactly is vibe coding according to the sources?
Vibe coding is an AI-assisted software development practice where developers describe a project in natural language and let AI generate the code. It was popularized by Andrej Karpathy in February 2025 and represents a shift towards intention-driven development, where the focus is on outcomes rather than traditional code writing.
How do platforms like Lovable and Claude Code support vibe coding?
Lovable provides full-stack app scaffolding with features like Plan mode, breaking work into 'bricks', and GitHub integration. Claude Code follows an agentic loop of gathering context, taking action, and verifying results, using tools like file search, code edits, and running tests to support the vibe coding workflow.
What are the key risks and challenges of vibe coding?
Vibe coding can lead to poorly maintained code if not approached carefully, with risks including unclear scope, lack of proper testing, and potential security vulnerabilities. The safest approach involves using guardrails like scope locks, permissions, tests, and clear ownership, often combining tools like Lovable for scaffolding and Claude Code for hardening and iteration.
