Yes, my brother explained it that way because he has a big screen TV and we thought it would be great to show his kids and mine "Back to the Future."
The kids asked many questions after they saw the movie and one of them was how you can still talk on a cell phone when you are in a building and there is a lot of cement all around.
He was not speaking to his fellow engineers, he was speaking to kids.
My metaphor, about the truth Mike Lindell was presenting and it would slip out no matter the barrier, was lost a few idiots.
What your brother said made perfect sense to me, but then I’m also an engineer (retired, though).
Your point is right on target.
