Last week I built a Solitaire game. Not because the world needed one, but because GPT-6 Astra had just released and I wanted to feel what it could actually do.
I picked a project close to home: an ad-free Solitaire game that runs in the browser, on any device, no login, no cloud, nothing leaving the machine. Draw 1 Klondike, three difficulty levels, the ability to resume mid-game, Chola and Mughal-era visuals, period-appropriate music.
One detailed prompt covered the brief. After that, three small tweaks and two rounds of corrections. That was the entire interaction. GPT-6 Astra, working through GitHub Copilot, wrote the code, set up the repository, and published it. I tested the finished game myself. No code review, no hand-holding.
The game itself is unremarkable. What it proves is not.
A working, polished product, in a category people used to build small businesses on, took one prompt, a handful of corrections, and a weekend. No team. No funding.
I have spent enough years around software to know what changed here and what did not. The Solitaire game never needed judgment. The brief was clear, the constraints were simple, and the output could be checked by playing a few hands. That is exactly the kind of task a model can now carry end to end, with a human only at the two ends: writing the brief and checking the result.
Most consumer utilities sit in that same zone. A converter, a habit tracker, a simple game, a single-purpose calculator. No network effect holds a user in place. No real infrastructure cost keeps a competitor out. The business case for these apps was never really the software. It was the cost of building it well. That cost has just collapsed.
This does not mean software is going away, or that everything is suddenly free. It means the question a founder building a utility-style product has to ask has changed. Not “can I build this,” but “why would anyone pay me to keep building this, when they can build their own version in a weekend.”
Apps built on integration, on switching cost, on data that compounds, or on infrastructure that is expensive to replicate, are not touched by this in the same way. Their advantage was never the code. It was everything around the code that a weekend prompt cannot reach.
When I work with founders in Chennai, this is usually the first question I push them on: is your product defensible because of what it does, or because of what it took to build it. After this week, the second kind of answer has a much shorter shelf life.
I still have the Solitaire game open on my laptop. It plays well, the artwork turned out nice, and I have already moved on to testing what else fits in a weekend. That, more than the finished game, is the part worth paying attention to.
If you want to see what all that took, the game is live to play here, and the code behind it, prompt-generated and untouched by hand, is on GitHub here.
