Chris McNulty and Microsoft MVP Andrew Connell explore the explosive rise of "vibe coding" — AI-assisted development from natural-language prompts — and debate the real-world risks, rewards, and strategic implications for today's business and technology leaders.

Takeaways

Vibe Coding Has Gone Mainstream. AI-assisted coding is no longer experimental. A GitHub survey found 92% of U.S. developers use AI coding tools at work, and Gartner projected that 60% of new code would be AI-generated by 2026. The global market for AI code-generation platforms has reached $4.7 billion, with projections of $12.3 billion by 2027. Collins English Dictionary cemented the trend by naming "vibe coding" its 2025 Word of the Year. [secondtalent.com] [strayspark.studio] [ndtv.com]

Speed Gains Come with a Comprehension Tax. A January 2026 Anthropic randomized controlled trial of 52 junior engineers found that developers using AI code assistants scored 17% lower on comprehension tests than those coding manually — averaging 50% versus 67% on quizzes — with the largest gap appearing in debugging questions. Productivity gains did not reach statistical significance. This confirms what Andrew warns: rapid output without understanding creates fragile systems. [infoq.com]

Microsoft's Copilot Strategy Is Fragmented. Andrew contends that Microsoft is "flailing" and "shipping the org chart," with multiple disconnected Copilot products that confuse customers. A Recon Analytics study of more than 150,000 respondents (July 2025–January 2026) found Microsoft Copilot's share as paid users' primary AI tool fell from 18.8% to 11.5% — a 39% contraction — while Google Gemini climbed from 12.8% to 15.7% and ChatGPT held roughly 55.2%. When all three platforms were available, only 8% of workers chose Copilot versus 70% for ChatGPT and 18% for Gemini.[reconanalytics.com]

"Agentic Engineering" Is the Mature Alternative to Naive Vibe Coding. Andrew initially "hated" the term vibe coding but came to distinguish between undisciplined prompt-and-ship and a professional practice he calls agentic engineering, a term he credits to technologist Simon Willison. In agentic engineering, the developer still reviews AI output, plans architectures, and catches errors — using AI as a force-multiplier for experienced judgment, not a replacement for it.

Developers Are Becoming AI Orchestrators. Chris and Andrew agree that the most effective AI-era developers act like development managers: delegating tasks to specialized AI agents (ideation, UX, debugging, documentation) and then integrating and verifying results. Andrew recommends organizations build an internal Center of Excellence — a handful of people who deeply understand AI tooling and can guide the broader team.

Entry-Level Talent Still Matters — IBM Proved It. Despite predictions that AI would replace junior roles, IBM announced in February 2026 that it is tripling its entry-level hiring, including for software developers. IBM CHRO Nickle LaMoreaux stated: "We are tripling our entry-level hiring, and yes, that is for software developers and all these jobs we're being told AI can do". IBM's rationale: cutting junior talent creates future shortages of mid-level managers and senior experts, and outside hires cost more and adapt more slowly. [finance.yahoo.com]

Quality and Security Demand "Vibe Checks." A December 2025 CodeRabbit analysis found AI co-authored code contained approximately 1.7× more bugs and issues and 1.4× more critical issues than human-written code. Meanwhile, a Fastly survey of 791 professional developers found that nearly 30% of senior developers report that editing and auditing AI output offsets most of their initial time savings. Code review must become a continuous, front-of-cycle discipline, not a final checkbox. [coderabbit.ai]

Quick Quotes

Andrew Connell — Founder, Voitanos

"I think Microsoft is flailing a good bit… They seem to be reacting to what other people are doing, and there's no real cohesive story across all of their M365 Copilot story."

"The one fear that I have with this is what is it going to do to the entry-level jobs? I have a very significant concern."

"I don't disagree too much with the statements coming out of the senior people at Anthropic that the title 'software engineer' could be gone by the end of 2026, probably by 2027. As much as I'm using it, I can see that."

"Right now the [Microsoft] plan just feels very reactionary. And that's frustrating to me."

Chris McNulty — Polaris Host

"Client after client we run into — they have a negative impression of Copilot because their belief is that the entirety of Copilot is the free little thing in the corner of the Edge browser."

"What you get is still proportional to the attention you put into it." — Chris McNulty, on AI-generated prototypes versus production-ready software

"Being successful with vibe coding or agentic AI software engineering… helps even more if you've come from a development manager background — I personally use different AI agents for different things."
