I tried the first one and it produced such a horrifying result from a photo of my husband and I and one of my drawings. XD I can't even show it here because it would cause sanity loss.
I could see it being useful in some ways, but since you do have to have a photo and a style image, I don't think it would work well since you would have to not only get those things but ensure you have the rights to use them too. I haven't checked to see what they say about copyright, but I wonder who the finalized image would belong to in this case. Even if it might not be a big deal now, someone might find a way to use it in an innovative way that is able to generate a lot of buzz and income and then the creators of the program may suddenly decide they deserve a piece of it.
I can say for the work I do, automation is very difficult. One of the things we have to do is background removal from images. Many users only have a JPG of their image and they need a transparent PNG. We have a tool that automatically does it with one click, however it really does not work well. It doesn't understand how to not be contiguous, can take out too much color, leaves a lot of artifacts, etc. So we end up having to work on those images regardless. Then there are poor quality images that we have to manually recreate or clean up.
We also have to vectorize images for production and anyone that has used Illustrator's Image Trace or Vector Magic will know that when it misses, it misses big time and some images just cannot auto-vectorize well because they are too low quality. Sometimes it doesn't even understand circles and text that is small don't even bother with. .-. Then it takes more effort to clean up the result than to just redraw it from scratch.
Our vectorized files also have to be a very specific way. An automation might be able to find some things... like if there are the wrong colors or a typo, but I don't think it would be able to do some of the specifics in the image itself.
So while an AI can make some illustrations, I think it would be difficult to do more specific tasks, working with low quality images, or generating content from nothing.
