In my opinion, computer science in general, not only artificial intelligence, is learned by doing.
Basically, You work on your project, you face problems (like memory management, security (yes there are security issues in AI), neural network training speed or efficiency). You post your code snippets here on stackexchange, and people will help you out.
That would be considered as a technical discussion, and I think it is more important than talking broadly about a subject that is meant to be very specific and detailed.
As others mentioned, you can find some good communities on reddit, and in different AI related topics, and people there are mostly geeks who would spend hours talking about the subject.
Or, if you do not find what you need, go ahead and create your new community.
There is also another option, yet one that I recommend, create a personal website, whenever you learn something new or have a new insight, write an article and make it possible for people to add comments and discuss the subject at hand. Always archive what you learn, your website will be like a reference or archive where you organize your knowledge.
Another option I recommend You actually can consider creating a medium.com account for this, and start writing about what you know right now, then you will start to make loyal readers with whom you can discuss whatever comes to mind.
Finally, if you want to study with other people, then here is an idea : search for beginners with ai related profile on linkedin , and send some messages asking them to join you, I do not think most beginners, who also want to study and learn more, will refuse.
Edit : And I forgot github.com or gitlab.com. Where people can view your code, and even work with you as a team. I highly recommend gitlab as you can create private repositories for free.
Among others, and once you find 2 or 3 interested people on linkedin, you can work together on skype, google hangouts.
Notice I do not recommend facebook, I personally tried it to chat with a team of developers, and it ended up being an element of distraction, none was really focused on the subject at hand.
Wish you the best.
