I built a fully working Mac utility in just 5 days, using a programming language I barely knew.
But this isn't another "AI replaces programmers" video.
I break down the workflow that made this possible: AI as a tool, Git and GitHub, open-source contributors, livestream feedback, CI/CD, and actually learning the code instead of blindly accepting whatever an AI generates.
The crazy part isn't AI writing software for us. It's how much leverage a single developer has when you combine all of these tools together.
In this video, I show the Mac utility, why I chose F# and .NET, how Git completely changes the way I develop, and why I think Git should be the FIRST thing every new programmer learns.
