So I’m sure some of you if not a good portion of you have heard about the idea that captchas are used to teach machines, and I don’t know enough about the topic to say if it’s true or not, it may just be a theory or objectively true, I honestly have no idea.

I just had a question about it; if it was true that captchas are used to teach machines, how does that even work? Captchas already have pre-set correct answers right? Doesn’t that mean that machines wouldn’t be learning anything new because the correct area for the object in that captcha has already been defined? Excuse my stupidity if there’s a simple answer to this, but like I said I have no idea about this topic and I’m just curious. Thanks!
