Tweaking that a bit, I think Captchas really need to change. But not with cut-off of grammar, which can be probabilistically (brute-force) broken. One can instead start asking simple questions presented over an image. For example, "how many blue dots on this pattern?" or "what animal is this?"(with a photo of camel or something). That's certainly going to be more manageable for humans and prevent us from behaving more like bots, and them like us. Of course, until the bots evolve a little more to circumvent this. It is so true that one often meets destiny on the path taken to avoid it. TLDR; Use image based 'A for Apple, B for Boy' aka the 'Kindergarten training' to filter out bots from humans. Ask questions that are human, to figure out humans in other words.
