Your points are well taken, and I think this is the fundamental struggle of anyone who works in a narrow and deep field. It's truly difficult to see things from a different point of view sometimes. It certainly could turn out that this ultrasound setup gives truly new information, but, it isn't really a new way of generating an image, it's the same physics we've used to generate images from sound waves for decades, and that modality comes with some pretty hard physical limitations that this demo does not directly address. Time will tell, if they don't run out of money. I'm hopeful!
