Incidentally, the computer tried to auto-correct “teh.” In fact, it auto-corrected again when I tried to type it in the previous sentence.
But that doesn’t mean computers are smarter than we are. In fact, this article from the Wired website says that ignoring typos is actually the sign of an intelligent brain.
Writing is a “high-level task” that generalizes the simpler stuff (e.g., letter + letter + a bunch of other letters = words) so that writers can turn those words into sentences that convey meaning.
We already know how the words are spelled, so we can skip over the incorrect use of its/it’s or the name of the person whose works we’re quoting. Thus when we see it “Freeman” instead of “Freedman,” it can look OK to us because we’re busy thinking about the concepts that our words impart.
Think that typos don’t really matter, as long as the meaning gets through? You’re wrong.
