You guys are absolutely on the right track. Cryptography solves this, but we have to sew cryptography into the world very deeply and wrap it around everything. I've been thinking about how the rise of AI is actually our friend because the pervasive insecurity of it is a forcing function for cryptography adoption.

Cryptography is the art of securing information.

The QC hoax needs to be dispelled and ECC needs to be pervasive and ubiquitous. The rise of spintronics, which looks very realistic, and to a lesser extent, photonics, should help make that realistic from a hardware perspective
