Invasive, untested and aimless procedure. The hippocampus controls more things than just memory, so zapping that region probably isn't a good idea. This sounds like the same bullshit sales pitch of electroshock therapy in the 1970s when it was marketed as a cure-o-tonic for all mental ills.

Until they get a slightly more specific understanding of how memory works beyond just "activity in the hippocampus", they should probably not be fucking around with this. My 2 cents.
