Well, surprisingly, that would only be as strong as doing OCR to get the words.

Why is that? Well, if you deliberately remove words that are easy to put back into the sentence, it's an easy task not because we humans are incredible at "out of the box" thinking, but because one or two word choices are orders of magnitude more likely than all the rest.

And when it comes to statistical guessing, computers are very good at that. Get a large enough corpus of the English language, and I can assure you that the probability distribution of the missing word, given that it's preceded by "I can't stand all" and followed by "your lies" is overwhelmingly in favor of "of".

Calculating these conditional probabilities is not a very hard task to program at all, though it does require quite some computational power and memory for longer chains.
