No matter how many patterns you have, you always need more. It's a huge evergreen niche. And a neural network here can do the job 60-80% faster
You can also make patterns on a computer, but it will be slower and less convenient than on an ipad
You have to understand where the capabilities of the neural network intersect with what is in demand. The first niche I recommend to start with is botanical patterns
The patterns the neural network will make will not be perfect. Often it will be necessary to refine them slightly, to redraw some parts in Procreate
