It’s not a loophole, it just happens that encoding information as optical tokens is much more efficient than text.

Not really. They arent actually using more resources this way either. This might be a fundamental inefficiency thats being removed

It kinda makes sense too. Because while people do read code word by word, we often "glance over" it and do roughly pattern recognition on it to know what it does. Only homing in on something when we need to answer a specific question. I think humans kinda naturally do this exploit anyway
