Togusa is very quiet for a long time, before he speaks up. "I saw a memory of a man with cybernetic eyes. They were- not just a visor, but mechanical units that went over where his eyes should be. I don't know if he could see on his own."

"But I'll admit I wondered what the world looked like to him. How could a machine simulate everything the brain does for us to see? Would it be even sharper vision in some ways, but missing information in others?" The suggestion Togusa is making is too clear to point out.
