Where will the apps be hosted? While AI can assist in creating a web app, its success depends on having sufficient computer resources to host it. For an unlimited number of successful apps, websites, and platforms, we would need an equally unlimited number of servers. However, when demand rises, so do the prices of these servers.

One potential solution is to move the AI onto customer devices. However, this approach is also limited by the resources available on those devices

YouTube videos are free, but some people manage to earn money with them.

Technology is getting cheaper, which means you can get the same product/service or even more for same or less money.

I almost agree with this, but I want to add that the poor people of the future will live no worse than today's rich, and even their housing will look luxurious compared to today's standards. The food will look like it was prepared in a top restaurant, with personalized design and cooking by robot chefs, which will become very accessible due to the decreasing cost of technology. If we compare the level of comfort that today's laborers can afford to that of the 19th century workers described in Dickens' books, we can see how much progress has been made. However, the rich of the future will undoubtedly benefit much more from a society based on artificial intelligence.
