<p style="margin:1em 0;font-family:-apple-system,BlinkMacSystemFont,'Segoe UI',Roboto,Oxygen-Sans,Ubuntu,Cantarell,'Helvetica Neue',sans-serif;color:#2d2d2f;font-size:16px;line-height:1.5">I've been writing code 100% AI-contributed for a few months now, and along the way it’s completely changed how I think about building software.</p>
<p style="margin:1em 0;font-family:-apple-system,BlinkMacSystemFont,'Segoe UI',Roboto,Oxygen-Sans,Ubuntu,Cantarell,'Helvetica Neue',sans-serif;color:#2d2d2f;font-size:16px;line-height:1.5">No, I <strong>haven’t</strong> bought into the hype, despite what the YouTube comments say. And I <strong>don’t</strong> believe that AI is a career-ending event for devs like you and me.</p>
<p style="margin:1em 0;font-family:-apple-system,BlinkMacSystemFont,'Segoe UI',Roboto,Oxygen-Sans,Ubuntu,Cantarell,'Helvetica Neue',sans-serif;color:#2d2d2f;font-size:16px;line-height:1.5">Quite the opposite, in fact.</p>
<p style="margin:1em 0;font-family:-apple-system,BlinkMacSystemFont,'Segoe UI',Roboto,Oxygen-Sans,Ubuntu,Cantarell,'Helvetica Neue',sans-serif;color:#2d2d2f;font-size:16px;line-height:1.5">Using AI to write software every day has changed my opinions — in some cases rewiring the way I think about the software engineering process entirely.</p>
<p style="margin:1em 0;font-family:-apple-system,BlinkMacSystemFont,'Segoe UI',Roboto,Oxygen-Sans,Ubuntu,Cantarell,'Helvetica Neue',sans-serif;color:#2d2d2f;font-size:16px;line-height:1.5">Instead of paying less attention overall, I find myself paying <strong>more</strong> attention in different areas.</p>

<p style="margin:1em 0;font-family:-apple-system,BlinkMacSystemFont,'Segoe UI',Roboto,Oxygen-Sans,Ubuntu,Cantarell,'Helvetica Neue',sans-serif;color:#2d2d2f;font-size:16px;line-height:1.5">Here are a few of them:</p>

<li style="padding:0 0 0 1em;margin:0;margin-left:1em">
<strong>Integration testing is everything.</strong> I'm spending way more time thinking about test boundaries and what I can safely delegate to AI.</li>
<li style="padding:0 0 0 1em;margin:0;margin-left:1em">
<strong>Deep modules with simple interfaces are king.</strong> Grey-box modules let you ignore what's inside the box and let AI handle the complexity.</li>
<li style="padding:0 0 0 1em;margin:0;margin-left:1em">
<strong>AI has zero taste for architecture.</strong> You have to be explicit about module structure and interfaces, or things fall apart fast.</li>
<li style="padding:0 0 0 1em;margin:0;margin-left:1em">
<strong>Prototype UIs aggressively before committing to a PRD.</strong> AI struggles iterating on existing UI, but excels when you give it a throwaway prototype to work from.</li>

Some will feel obvious in hindsight. Others will feel counterintuitive at first.</p>
