My question has similarities to this one, but also has other aspects to it. The answer points out that the top tags on all three websites differ. But here are a few points to consider:
In practical scenarios, people working in one of these areas end up using all of these sites due to overlap in technical topics. There is a lot of overlap between the technical topics and their underlying principles.
Right now, the computer-vision questions are divided between various Stack Exchange websites like Signal Processing, AI, Computer Science and others. Even Stack Overflow has theoretical computer vision questions. If the above sites are combined to the AI Stack Exchange and computer-vision questions are moved there, the site will grow in popularity and computer vision will have a good home.
This will also help new emerging topics related to AI as the website will grow from the merger. Right now, a very small number of people know about the existence of AI Stack Exchange. Also, this site does not encourage implementation questions. So, if not combined, will this site ever have any significance?
Users often find it confusing to figure out where to post their questions.
Is there still a possibility of combining these sites? I am also curious if this idea would work out better if Data Science is taken out and only the other two are combined with computer-vision topics?
