Gergely Orosz's edited clip of me talking about Open Source. Gergely Orosz released this clip to help promote our podcast conversation AI tools for software engineers, but without the hype - it's a neat bite-sized version of my argument for why Open Source has provided the single biggest enhancement to developer productivity I've seen in my entire career.

One of the big challenges everyone talked about was software reusability. Like, why are we writing the same software over and over again?

And at the time, people thought OOP was the answer. They were like, oh, if we do everything as classes in Java, then we can subclass those classes, and that's how we'll solve reusable software.

That wasn't the fix. The fix was open source. The fix was having a diverse and vibrant open source community releasing software that's documented and you can package and install and all of those kinds of things.

That's been incredible. The cost of building software today is a fraction of what it was 20 years ago, purely thanks to open source.
