Software 2.0: Demystifying the Future of Coding

Remember the days of clunky software riddled with bugs and limited functionality? We've come a long way since then, but software development is about to take another leap forward - enter Software 2.0.

Coined by AI expert Andrej Karpathy, Software 2.0 refers to a paradigm shift where machine learning (ML) takes center stage in building software. Instead of humans hand-writing every line of code, this new approach leverages the power of neural networks to learn and automatically generate code, paving the way for a future of faster, smarter, and more adaptable software.

So, what's different in Software 2.0?

  • From code to data: Instead of writing instructions, developers provide large datasets representing the desired outcome. Imagine telling a child what a car does instead of explaining how an engine works. The ML model analyzes the data, recognizes patterns, and "writes" the code to achieve the desired goal.

  • Learning on the fly: Software 2.0 applications continuously learn and improve with new data. Think of a self-driving car that gets better at navigating with every mile driven. This adaptability allows software to adjust to changing environments and user needs.

  • Automating the mundane: Repetitive tasks like generating basic code or optimizing algorithms are handled by AI, freeing up developers to focus on creative problem-solving and complex functionalities.

What are the benefits of Software 2.0?

  • Faster development: Building software can be significantly faster by automating tedious tasks and leveraging the power of ML for complex calculations.

  • Enhanced functionality: Neural networks can tackle problems beyond human coding capabilities, leading to more sophisticated and intelligent software.

  • Accessibility for all: With AI assistance, coding could become more accessible to individuals with less technical expertise, potentially democratizing software development.

Are there any challenges?

  • Black box problem: As ML models learn on their own,understanding their decision-making process can be difficult,raising concerns about transparency and explainability.

  • Ethical considerations: Bias in training data can lead to biased software, necessitating careful attention to ethical implications.

  • Job displacement: While new jobs will be created, some roles in traditional software development might be automated, requiring workforce adaptation.

Software 2.0 is still in its early stages, but the potential is immense. This evolving landscape promises to revolutionize the way we build and interact with software, ushering in an era of intelligent and dynamic applications that adapt to our ever-changing world. The key will be to embrace this transformation while addressing the challenges responsibly, ensuring that Software 2.0 empowers humanity and creates a more equitable and technologically advanced future.

As we peer into this new world, Secret Chest has explored various options. It would be irresponsible not to, at this point. We created an Xcode Plug-in to help us write unit tests, which we open sourced at Along the way we came up with a few little tips:

  • Comment every line of code you import. Users of TestFairy highlight a stanza of code and then ask it to write unit tests, improve the code, or do a few other tasks. Every line of code we import is commented. It's a simple ( ⌘ + / ) to uncomment selected lines of code in Xcode, but we wanted to force developers to review it, or at least to perform a manual task, hopefully after reviewing it.

  • Make simple requests. As of the time of this writing, it's not possible to use some low code tool and ask a Copilot, Google Bard, or ChatGPT to "write me an accounting app." Instead, pseudo-code an app, or a larger atomic process, and then try to get them to write the functions from the pseudo-code. For example, "write me a function in javascript to lint json" and then "write me a function in javascript to commit a json document to mongodb" and then write me a function in javascript to lookup the tax for a physical address supplied as another json document using the Avalara API" and so on.

  • Specify the version you're using. For example, a default response might be swift 2, when the latest is swift 5, and nothing in the swift 2 output actually works.

  • Be as specific as possible. Notice in the above we were including the language, perhaps the version (if applicable), the API, etc. The more specific, the more likely there will be certain bits of logic that make something actually usable.

Again, we're not building full apps or webapps with AI at this point. We might get there some day, but not quite! A good developer can get a lot more done quickly in this new paradigm, though! Just make sure it's quality software and not the programmatic equivilent of a crappy blog post that's going out!
