Yes, I agree. It's notable, for instance, that most of us are
especially good at picking out our own names amid noise and
distractions... this result seems to be comparable to that.

It's still quite impressive; picking out anything with 1000 times
as much noise as signal seems like quite an achievement. But it
doesn't sound to me as if it's going to change the world.
