展示HN：GPT帮助我在30分钟内重建了一个.NET应用，而在MFC中花费了3周时间。
我从未使用过 .NET，对 .NET 或 VB 一无所知，也只了解 VC++ 和 MFC。<p>最近，我尝试了一下 GPT，逐步引导它，并请它帮我重建一个我最初用 MFC 编写的工具。令我惊讶的是，它成功了：一个完整的 Excel 转 PDF 自动化应用程序，在 30 分钟内完成；其中包括一个我认为 AI 处理起来会很棘手的小算法。<p>我甚至没有理解代码中的任何一行，只是不断提问、复制和运行。<p>这感觉既令人惊叹又让人恐惧。如果 AI 现在能做到这一点，五年后会发生什么？<p>这是我制作的一个 5 分钟视频，展示了整个过程和真实代码的运行（没有剪辑，只是加速）：<p><a href="https://youtu.be/-mf_yOhOCfs" rel="nofollow">https://youtu.be/-mf_yOhOCfs</a><p>我并不是在推销什么，只是分享让我震惊的事情。

I've never used .NET, know nothing about .NET or vb, or anything outside vc++ & MFC.<p>Recently I gave GPT a try, guiding it step by step, and asking it to help me rebuild a tool I originally wrote in MFC.
To my surprise, it worked: a full Excel-to-PDF automation app, done in 30 minutes; including a small algorithm I thought would be too tricky for AI to handle.<p>I didn't understand even a single line of the code, I just kept asking, copying, and running.<p>It felt amazing… but also terrifying.If AI can do this now, what happens 5 years from now?<p>Here's a 5-min video I made showing the full process with real code running (no cuts, just sped up):<p><a href="https://youtu.be/-mf_yOhOCfs" rel="nofollow">https://youtu.be/-mf_yOhOCfs</a><p>Not selling anything. Just sharing what shocked me.
