Lindsey Graham came around. Sam Harris changed his point of view after a fairly combative initial stance against technologists.
We will never know if we can inform the public unless we try. There are some good analogies out there supporting encryption. Use them. I recommend the one from Sam Harris' third video on the subject. There is also the whack-a-mole argument.
Honestly, the biggest thing standing in the way of the public being informed is not the unwillingness of the public to listen. It's the technologists' unwillingness to try to educate them.
I understand your trepidation. In life, we scientists are often ignored. But sometimes we are right and I do feel if we push hard here we can figure out ways to reach people.
