Most (?) technicians don't know much about the techniques behind their tools!
This was a great source of disappointment when I was a kid and I asked the electrician how the CRT in a TV worked, or why the plane flew (from a pilot), or how a nuclear reactor worked (from an uncle).
I got my teeth 3d scanned at the dentist, I asked the lady if she could send me the 3D file. She looked at me like I had kicked a puppy and said “I’ve never heard of anyone asking for that…” like lady, it’s MY mouth. I want to 3d print my mouth as a gift to my friends. Not weird
