Hate to rain on this person's parade, but his findings are mostly meaningless. You cannot simply infer neurological activity from a single electrode. Besides the need for a proper ground/reference, you also need electrodes placed in the correct anatomical locations to derive any meaningful insights into attention networks.
Unless something has happened to drastically alter EEG analysis since last I checked, this is meaningless with one electrode. You need at least one other specifically to measure eye/muscle movement, etc.
People are way too negative. This guy is trying something and showing what he did. Not every discover came from proper scientific laboratory or with a standard procedure. Instead of hating what he is doing, I would encourage him to go further. In my opinion, I prefer those kind of research than nothing at all and found interesting his conclusion. Keep trying and improve and some day it will be probably something.
