To dissipate or distill by percolation.
Mr Lanier strikes again.
When I came across the sentence, «The strangeness is being leached away by the mush-making process» in You Are Not A Gadget I thought at first that I’d stumbled across a typo that had escaped the editor’s eye. I expected that he meant leeched as in, sucked away as though by a parasite. While this would have made enough sense, Lanier’s choice indeed seems more appropriate.
Fortunately, I thought for a moment about who was more likely to get the usage right, myself or Jaron Lanier. Since two Lexical geekery entries have previously been entered from the first fifty pages of this book (and I’ve bookmarked a third encountered before this one) it seemed prudent to check the dictionary before proceeding.
