> selling apps gets more and more difficult

Yes, but also people in the HN bubble overestimate how many people would want to sit down and "prompt their own app". Just like I mostly don't want to bake my own bread and leave it to the professionals at the bakery.

I might be excited about doing my own music library management script, but probably less excited about building my own Photoshop if there's already a company in that space focusing on that as their core business.
