Why do you have to waste ultra-expensive engineers on it? You have agents. And verifying your product works as it is claimed should absolutely be part of your mission. How can you possibly claim that your models are revolutionising software development if you haven't even used them to revolutionise your own software development in-house? Not only that, it would produce a huge marketing coup that would immediately lead to a flood of enterprise spending if you could demonstrate that your agents actually do what you constantly claim them to do.
PS. If you're claiming that coding an application is ultra-expensive, you are already entering the argument on the side of the comment you're arguing against, which is making a counterpoint to the article, which claims in the first sentence:
> The math is simple: if it costs almost nothing to build an app, it costs almost nothing to clone an app. And if cloning is free, subscription pricing dies.
They did revolutionise software development in-house. Both Codex/Claude Code are 90% agent written these days, and bring in billions of dollars of revenue.
Cloning Slack would bring in $0 dollars.
