With the rise of laser, microwave, and energy weapons, we are returning to a time of armor.
Copper or silver chainmail disrupts emfs.
Kevlar or silk underneath will slow projectiles.
Metal shells with ornamentation - angular lines, mirrored surfaces, rounded corners, will prevent detection and blunt force.
With all new cars being vulnerable to hacking and control, horses will become a viable option for mobility again.
So let them move towards "the future". We will become beautifully armored knights again. With purpose.
Put a cellphone under it. Put it over a TV antenna. A wifi router. Etc.
Theres probably great items out there made by real people with a real purpose, but there is a lot of snake oil as well. Look at all the "emf" stickers and other bullshit on the market.
