Of course, LC-only won't get you there, and all companies with LC use the whole arsenal. But I don't doubt that LC will filter out a very large fraction of applicants (hence the incessant whining on HN). The point is though, with Google-like application volumes, if they drop LC they'll need to substitute it with something that also filters out a very large fraction.
The actual hiring ratio at google is something like 0.2%. They pass over 998 out of 1000 applicants, so no matter what they do, they'll pass over a substantial number of qualified people, and no matter what they do there will be complaints on HN.
