Whats a good example of nondestructive creation?
Thirty years ago, the only diagnostic techniques that people used to use were X-rays. We still use a lot of X-rays. But then we had CT scans, then PET scans, and now we have MRIs. And with each of these innovations, we now can diagnose diseases that you wouldn’t have been able to diagnose previously. So it’s not that MRIs simply substituted for X-rays. In fact, most MRIs are used to do things that X-rays could not do. An X-ray could not show you a tumor in your back because of the soft tissue. So an MRI is largely an example of nondestructive creation. In addition to helping the early detection of tumors, it also created a whole bunch of jobs, both for radiologists and for the people who maintain the MRI equipment and the technicians who operate it. And because this keeps happening, we shouldn’t worry if some X-ray reading goes off to India.
