How hard would it be to create an AI to auto-answer Stack Exchange questions?

This largely depends on the Stack Exchange API and API Terms of Use….

1. First, you need to check the Terms of Use to determine if this would be allowed or not.
2. Then you need to check the API functions to see if they enable both read and write access, if not search access.
3. You then need to think about your source of answers.  For instance, if you can search Stack Exchange with the API then you may be able to source appropriate answers that have been posted previously (see Recommender Systems).
4. You could then look into Automatic Summarization and Natural Language Generation to create new and unique answers out of your database of prior answers.
