“AI belongs to everyone, it's not limited to computer scientists only”
Anyone who has a good/expert knowledge in any one field or a vast variety of subjects.
AI is a multidisciplinary science. You cannot say what knowledge or concept of which subject can prove to be very helpful in solving an AI problem.
There are no fixed/narrow/pre-defined/ methods/approach in AI. AI is open to take whatever it can from any discipline of academic study and research. This is to say anyone from any discipline can hugely contribute in the advancement of AI techniques.
You can be from a finance background or you may be a historian who has observed some pattern in accounting methods/human evolution which can be helpful in AI to develop/add certain capabilities to it.
All I can say is that it's very interesting and expands your understanding of humans, nature.
