If these existed, would people continue attempt to cross illegally? The thought-provoking argument is that these pieces of technology, if foolproof, would go completely unused as people inherently value their lives (but not laws.)

I wish I could have lived in a bubble, developing "tech" that didn't matter and was only positive, but even the most disconnected web jockey is paid for by the surveillance-capitalism dollars of the modern internet. That tech might be worse for society overall - it gave us the creeping global eye at a pace faster than legislation could keep up with it, or that society could adapt, and it seemed innocuous at first.
