The Germans were both curious and skeptical about this new technology.
Often, something too advanced proves to be its own stumbling block. The development of new technology usually undergoes an iterative process, from inception, to development and maturity, tending to ascend spirally.
That process is not led by an individual, but by a group of people or several generations.
So, any new technology has a trajectory, but it seems that this new technology didn't have a rational one. It just suddenly appeared and went straight for clinical trials.
This left the audience puzzled, with a lot of unanswered questions in their minds.
However, given the forty successful cases that they knew about, there was no room for skepticism.
No matter how medical science evolves, it is still a practical science. The effectiveness is in the practice. The technology proven to be safe and effective.
