A grocery list app is the perfect example of the kind of thing that AI will make obsolete. Why would I pay $5/month for a list app when I can pay Claude $0.30 one time to make it for me?

I in fact did just that. I used Claude to reverse engineer my grocery store's API and build a grocery list app that automatically pulls in the aisle information for each item and sorts it by how I typically walk through the store. It's the kind of thing that would be incredibly difficult to scale but works just fine when you only have one user. No SaaS grocery app can hope to compete with me being able to tailor my own shopping list app to my exact preferences.

> reverse engineer my grocery store's API

Your grocery store has a free API you can use? Even if that is the case, that will then soon change. If app building becomes "free" then the cost will shift over to the data access.

Who pays $5 per month for grocery store apps anyway? The usual revenue model is the app is free and you pay for the groceries...

I think an engineer might, but my mother and wife will certainly pick the $5/mo option every time.

That is exactly the type of awesome app that can now be built. I edited my comment to clarify that the grocery app and $5/month app are separate examples, but I think your example shows that someone with coding knowledge can build something extremely useful for n=1 users which I fully support.

I just don’t think most people will end up doing that just like how most people don’t 3D print their own desk drawer organizers even when Gridfinity does all the work for you. Automation doesn’t fully replace the volition to build a thing and make tricky decisions that are familiar to us software engineers but not others.
