The A.I. Disruption We’ve Been Waiting for Has Arrived

On weekday evenings, heading home on the subway from Union Square in New York City, I log into an A.I. tool from my phone and write a prompt. “Look at the data in the files I just uploaded,” I tap. “Load it into a database, then make it searchable with a web interface.” Underground in the subway tunnels my internet connection drops, but when my train emerges onto the Manhattan Bridge, I get a few minutes to see all the work my coding agent has done, and if I type fast enough I can issue another prompt. By the time I get home to Brooklyn, my little project tends to be done: a website, a feature in a music app, a complex search tool or some tiny game.

This is called “vibe coding,” a term coined a year ago by the artificial intelligence expert Andrej Karpathy. To vibe code is to make software with prompts sent to a specialized chatbot — not coding, but telling — and letting the bot work out the bugs. Like many other programmers, I use a product called Claude Code from Anthropic, although Codex from OpenAI does about as well, and Google Gemini is not far behind. Claude Code earned $1 billion for Anthropic in its first six months. It was always a helpful coding assistant, but in November it suddenly got much better, and ever since I’ve been knocking off side projects that had sat in folders for a decade or longer. It’s fun to see old ideas come to life, so I keep a steady flow. Maybe it adds up to a half-hour a day of my time, and an hour of Claude’s.

November was, for me and many others in tech, a great surprise. Before, A.I. coding tools were often useful, but halting and clumsy. Now, the bot can run for a full hour and make whole, designed websites and apps that may be flawed, but credible. I spent an entire session of therapy talking about it.

The tech industry is a global culture — an identity based on craft and skill. Software development has been a solid middle-class job for a long time. But that may be slipping away. What might the future look like if 100 million, or a billion, people can make any software they desire? Could this be a moment of unparalleled growth and opportunity as people gain access to tech industry power for themselves?

According to the market, the answer is no. Recently, software stocks — Monday.com, Salesforce, Adobe and many others — plummeted all at once; the Nasdaq 100 lost half a trillion dollars in two days. Legal software company stocks slumped recently because Anthropic released tools to automate some legal work. Financial services firms and real estate services — the market keeps devaluing them because traders expect there to be less need for humans at desks in an A.I.-automated future. Why will anyone need all that legacy software when A.I. can code anything up for you in two shakes of a robotic lamb’s tail?

Personally this all feels premature, but markets aren’t subtle thinkers. And I get it. When you watch a large language model slice through some horrible, expensive problem — like migrating data from an old platform to a modern one — you feel the earth shifting. I was the chief executive of a software services firm, which made me a professional software cost estimator. When I rebooted my messy personal website a few weeks ago, I realized: I would have paid $25,000 for someone else to do this. When a friend asked me to convert a large, thorny data set, I downloaded it, cleaned it up and made it pretty and easy to explore. In the past I would have charged $350,000.

That last price is full 2021 retail — it implies a product manager, a designer, two engineers (one senior) and four to six months of design, coding and testing. Plus maintenance. Bespoke software is joltingly expensive. Today, though, when the stars align and my prompts work out, I can do hundreds of thousands of dollars worth of work for fun (fun for me) over weekends and evenings, for the price of the Claude $200-a-month plan.

That’s not an altogether pleasant feeling. The faces of former employees keep flashing before me. All those designers and JavaScript coders. I could not hire the majority of them now, because I would have no idea how to bill for their time. Some companies, including IBM, think A.I. will create tons of new jobs. But no one thinks they’ll be the same as the old jobs.

Is the software I’m making for myself on my phone as good as handcrafted, bespoke code? No. But it’s immediate and cheap. And the quantities, measured in lines of text, are large. It might fail a company’s quality test, but it would meet every deadline. That is what makes A.I. coding such a shock to the system.
