I don't see these things as equal, but I see where you are going with the comparison. Both require an understanding of a specific domain and problem(s) that need to be solved in that domain.
I really think striving to find specific problems where AI can add value is critical to making money in the space, and I agree with this article strongly.
The term "AI" is so overused that it can mean anything. Expert systems are considered "AI" for that matter. They may not necessarily use the most computationally expensive methods like neural networks, but "AI" doesn't prescribe any specific technique.
