As the old joke goes, "AI" is anything that doesn't work yet.
Once an "AI" system becomes reliable, we quickly take it for granted and it no longer seems impressive or interesting. It's just a database. Or an image classifier. Or a chatbot.
I'd argue a database is possibly as far from an AI as you get. Indexing and data structures and storage systems that go into them are very deterministic data structures you can model out and roughly know the behaviour of before writing a single line of code. Image classifiers and Chatbots you don't know what you're getting out till you train it and deploy it.
