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.

I didn't understand even a single line of the code, I just kept asking, copying, and running.

It felt amazing… but also terrifying.If AI can do this now, what happens 5 years from now?

Here's a 5-min video I made showing the full process with real code running (no cuts, just sped up):

Not selling anything. Just sharing what shocked me.
