Vibe Coding Has Grown Up: What Career Changers Need to Know

AI can now turn plain-language ideas into working apps, but speed without scrutiny creates risk. Here’s how vibe coding has matured, what “doomcoding” warns us about, and why coding fundamentals give career changers the edge.

In February 2025, Andrej Karpathy gave a name to something developers were already experimenting with: generating code by giving instructions to an AI. Since then, vibe coding has grown from a clever shortcut into a far more deliberate way of working. With tools that can now handle whole projects, it has become a proper back-and-forth of describing what you want, generating it, checking it and refining it.

But cutting corners on that checking stage can leave hidden problems in otherwise great-looking apps, something people are now calling "doomcoding". Understanding the basics of coding helps you spot when AI has got it wrong, rather than just taking its word for it, reiterating why coding skills remain valuable and sought after in the UK job market. 

In this blog, we will talk through the history of vibe coding and how it has evolved, the risks of skipping proper checks, and why coding fundamentals still matter if you’re considering a career change into tech.

From One Clever Prompt to Intent-Driven Engineering

Early vibe coding looked refreshingly simple: you described an idea, the AI generated the code, and you adjusted your prompt until it worked. People loved it because it closed the gap between an idea and a working prototype, and let you focus on the outcome you wanted instead of typing every line by hand.

IBM's guide to vibe coding shows how far that approach has come, with the workflow now running on a repeating cycle of intent, generation, review, and refinement. Developers examine what the tool has produced, adjust the requirements, and generate another version. 

They might change a feature, improve usability, or rethink the structure rather than accepting the first result. The developer still sets the direction, supplies the right context, checks the output carefully, and decides what happens next, meaning producing code faster isn’t necessarily the priority.

Context Shapes the Result

A vague request leaves the tool guessing, whereas a useful brief spells out who the software serves, what it must do, and which constraints it must respect. 

For a habit-tracking app, that could mean defining how users record progress, what the charts show, and how information is stored. The first output is still a draft, but a clearer brief gives the next round of review something concrete to test.

A New Toolset Is Expanding What Prompts Can Do

Platforms like Replit, Cursor, GitHub Copilot, Windsurf and bolt.new now do far more than generate isolated snippets. Depending on the tool, the AI can reason across multiple files, debug errors, run commands and help with deployment. 

Vibe coding increasingly feels less like typing prompts and more like working alongside an active technical assistant.

That opens up genuinely useful paths, from rapid prototyping to minimum viable products to cheaper, lower-stakes experimentation. A team can test whether an idea is worth pursuing before committing to a full build, and an individual can turn a rough concept into something visible and interactive much sooner than before.

Did you know? 84% of developers now use or plan to use AI coding tools

According to Hostinger, this is up from 76% in 2024. Even so, only about half of professional developers (51%) rely on them every day.

"Doomcoding" Is A Warning, Not a Verdict on AI

The debate has acquired sharper language; for example, in a September 2026 opinion piece for Inc., Joe Procopio used the label "doomcoding" for the problems now creeping into AI-assisted development. The term lands because rapid generation can tempt people into accepting code they don't actually understand, especially when the app seems to work fine.

A Futurism report adds a more tangible warning through an anonymous engineer's account of one company using Claude Code heavily. The engineer describes long days approving AI output while bugs remain unresolved. One workplace account isn't a measure of how software teams everywhere operate, but it raises the right question: can people explain, test and improve what the tool produces? Faster generation has little value if fixes keep piling up.

This doesn't necessarily mean vibe coding has failed; it simply shows what happens when speed outruns scrutiny. Production software still needs:

  • Human code review
  • Structured testing
  • Checks on third-party components and dependencies
  • Security assessment
  • Proper deployment governance, including confirmation that generated code meets your organisation's standards and legal requirements

Skip those steps and the shortcuts pile up - hardcoded credentials, exposed passwords, unsecured APIs, insecure connections to other services, vulnerable libraries and injection flaws can all hide beneath a polished interface. 

Fixing that security debt later usually costs far more than building carefully in the first place. AI makes it easier to build a first version, but it doesn't make those checks disappear.

What Does This Mean If You're New to Coding?

If you're exploring coding for the first time, vibe coding makes experimentation feel much more accessible. You can build small projects, test ideas and see real results without mastering every tool up front. At Learning People, we see it as a practical way to explore software development, and you don't need to master a programming language before trying a small idea.

That said, our guide to getting into coding explains why the fundamentals still matter. A working knowledge of Python, HTML, CSS or JavaScript helps you question AI output instead of trusting it blindly. Here's a simple way to start:

  1. Ask AI to draft a simple app
  2. Learn enough coding to follow its logic
  3. Change one feature and test what breaks
  4. Repeat, with slightly bigger projects each time

Your experience solving problems in another career gives you a head start, while coding fundamentals help you judge whether the result actually works. Practise consistently, take the time to understand how the software works, and let AI speed up your progress rather than replace your judgement.

Build Coding Skills That Keep You in Control

Our coding training can help you build the core knowledge you need to use AI tools with confidence and real purpose, developing the fundamentals alongside practical AI use. And if secure development catches your interest, our cybersecurity training adds hands-on skills in vulnerability assessment, risk and safer deployment, a natural complement to coding.

If you're considering a career change, you may already have the human skills that employers struggle to find, and you may be able to evidence them clearly. Managing deadlines, calming difficult situations, training colleagues and solving problems all demonstrate valuable capabilities. This is also the kind of judgement that AI-assisted coding relies on, since someone still has to decide whether the output is good enough. Technical training can then provide the credentials your target role requires.

Our career pathway training programmes combine recognised technical training with sector-specific AI learning and career support. Explore the route that fits your experience, then build the technical, human and AI skills employers now expect by booking a free career consultation with a Learning People career consultant.
