In this high technology era, privacy is no more. If sent electronically it is recorded somewhere, probably the huge NSA facility in Utah. The listen and record the data. I would suggest that most of that computing power is to glen all the data and flag up unusual data for human eyes to look at and more and more AI. Our adversaries have the same, particularly China.
The electronic genie is out of the bottle and it can not be put back in.
Odd story about my friends cell phone. He and I shoot together and often discuss different weapons. One afternoon we were doing such on his back porch. A few minutes later he got and email advertisement for not just a weapon but the exact one we were discussing. What are the odds?
“What are the odds?”
My sister and I were sitting on a bench outside of a surgery center waiting for my brother to be discharged.
About halfway way home, Sis said, “Oh, I forgot my water bottle on the bench.” She said she didn’t want to bother going back for it.
About a half hour later, she was getting ads on her cell phone AND her PC (????) for water bottles.
