Text is easy to parse. But hard to analyze. And even if it were easy to
analyze, you could still present puzzles that will beat every machine.

How many words are in this sentence?

There's no need to get into an arms race about reading garbled
characters and letters off some image. Yes, computers are able to do

endless resources on the spammers' side for the arms race.
