In this excerpt from ernest hemingway's "in another country," which sentences show the distrust the soldiers had toward new technology and medicine in the postwar era?

I think that these sentences from the Ernest Hemingway's "In Another Country," show the distrust the soldiers had toward new technology and medicine in the postwar era:

“The major came very regularly to the hospital. I do not think he ever missed a day, although I am sure he did not believe in the machines. There was a time when none of us believed in the machines, and one day the major said it was all nonsense. The machines were new then and it was we who were to prove them. It was an idiotic idea, he said, "a theory like another".”
