I think azan_ is demonstrating that shipping products 'suitable for the needs of many' is going to have to compete with 'slopping software for the needs of one'.
There is a small subset of the population who is now enabled to make proof-of-concepts with less effort than before. This is no way diminishes the need for delivering performant, secure, interoperable software at scale to serve humanity's needs.
I'm going on a tangent here but what's with this constant deprecation of mothers to make a point? There are many people here whose mothers can develop software.
I think the thing you're missing is that the tool doesn't need to be marketed because someone else could ask their LLM to make them a similar tool but fitting their use case.
It doesn't matter if the tool "needs" to be marketed. There is a market of paying customers. If other people are paying $200/month, both your and their lives would be improved significantly by you offering a $100/month replacement software. For all the talk about LLMs replacing the need for packaged software, people are still paying for packaged software, and while they are, you could be making large amounts of money while saving them money. If you're altruistic, you could even release it as FOSS and save a lot of people $200/mo. Unless, of course, your vibe-coded app isn't actually remotely capable of replacing the software in question.
