Under the URL https://ai.stackexchange.com/search?q=answers%3A0 a list of open questions is given at the SE.AI website. The problem is, that the number grows. Last month the record was around 390. Now it is 403. The problem is, if nobody answers the open questions, the website will look bad. Questions which have no answer are too hard for the community, that means it looks like the users are overwhelmed. Are the questions hard to answer? Sometimes. Some of the questions are 1 year and older. They are remaining in the database. It is not the fault of the OP, but of the community in SE.AI. The problem is, that the ressources are limited. And asking a question is easier than posting an answer.
To overcome the problem it would be necessary to increase the effort, which means that more AI-experts are needed which are motivated to increase their reputation by answering questions by beginners. The task itself is easy, all what the user needs to know is a bit English skills, a working browser with Google Scholar and the goal to bring AI forward. But i would guess, that it is hard to find such people, so my prediction is, that the number of unanswered question will raise further.
