I'd say if you're a semi-competent developer, as probably many people reading the article and commenting already are, this comment adds nothing new to the discussion and would already be a very vanilla usage example of "AI".
I think the point is that while you can "do things" like extracting the stripe integrations out into their own service in ten minutes, you're not stepping into other problems, such as how do you handle failures, how do you scale the stripe service, how do you structure all your other micro services so they can communicate in a coherent way, basically you're speed running yourself into harder decisions when using AI.
