The wave walls are more stable than traditional walls. Very sensible and practical design.
It is really only a benefit if you are replacing a cinder block construction wall. Which there a now robots that will assemble a block wall too. Instead of having multiple human masons.
I could see these being practical in FL, or the SW US as a replacement for Adobe style construction. It would also be good in places that are prone to forest fires. Like California. I am not sure how they would handle an earthquake.
