Part of the reason for this is that very often the best applications of AI are really invisible to the user, making everything a little bit better, quietly behind the scenes.
The same is true for software in general. The best software products automate loads of stuff behind the scenes so from the user perspective they just click a button and the thing they want to happen, happens.
Perhaps the most successful and important AI product is a great example of this: the spam filter. I bet most younger email users don't even realize how much value this old AI tool provides them unseen.
But the trouble is making effective AI products is not "sexy" right now, and if your team ships one it won't get any credit in a big company. I've had my PM instantly shoot down plenty of interesting applications of AI that wouldn't be very visible to the customer or larger product-org.
