Good job on creating a firewall for people who have poor vision.

So are we going to end up at a point where AI spends vast computing power reading things any that humans don't want them to read, while the humans get a worse experience because everyone is bending over backwards trying to stop the AI reading things.

Captcha was bad enough.

>Most AI systems work by reading the pixels of an image up close.

Not really, most AI systems work by reading the octets as ASCII/unicode (and then tokenizing it).

You could make an even better decoy font that renders one letter as another, so when you copy and paste it onto some other place with a normal font it reads as garbage, and garbage is what the AI will see, however if you render it with the descrambling font, you will see the regular message.

This has been used in PDF files as an obfuscation and anti-copy mechanism.
