The failure mode is getting lumped into AI because AI is a lot more likely to fail.
We've done this with Neural Networks v1, Expert Systems, Neural Networks v2, SVM, etc, etc. only a matter of time before we figured it out with deep neural networks. Clearly getting closer with every cycle, but no telling how many cycles we have left because there is no sound theoretical framework.
At the same time, we have spent a large part of the existence of civilisation figuring out organisational structures and methods to create resilient processes using unreliable humans, and it turns out a lot of those methods also work on agents. People just often seem miffed that they have to apply them on computers too.
