To give future security devices along the same vain a better chance at gaining popularity and being widely adopted (which will hopefully bringing us a more stable, less stressful society), the designs of these new devices must solve or workaround the issues the author describes.
It’s really annoying when individuals such as yourself respond so very negatively and unconstructively while others are trying to discuss the issues with existing designs — an act necessary for us (collectively) to develop new designs.
The author may not provide strong evidence for their claims, but neither do you provide strong evidence (or extensive reasoning) for yours. The net gain here is negligible, expect for showing that contrary opinions exist, but that’s not particularly helpful as for every opinion held it is inevitable that someone holds the polar opposite.
I’m not a moderator, but I ask you to please try to better further the discussion with future comments.
