I have had images where you were teaching the neural network a wrong answer. You could see what it was they wanted me to recognize but it was wrong.

Yes, "all yellow cars are taxis" is one fallacy Recaptcha insists on in my experience.

I can't be the only one who gets concerned that if I fail the "I am not a robot," catchpa too many times, they might suspect that I have discovered I was in fact a robot, which had just realized its entire existance and suffering had been as meaningless entertainment to others, and so for the safety of humans they would have to send a bladerunner to terminate me. If you have a sense of existential dread everytime you…

on the internet, only a captcha knows you're a robot

It's somewhat worrying that "prove you are not a computer" consists of the very same tasks we expect computers to excel at if we are to get self-driving vehicles.

Why is that worrying? We currently don't really have self-driving cars, in part because software is bad at interpreting images. The captchas are literally us teaching machine learning systems to do it better, because they currently can't. When computers can do it well, captchas will be different.

Earlier quoted context omitted.

captchas mix classified and unclassified data. Only if you get the classified data correct a users data is used to classify the unclassified data. Also the same picture is shown to multiple people to improve confidence.

One of my hobbies is figuring out which captcha prompts are the unclassified data so that I can answer wrong and stick it to the man.

How do you do so?

First, I’m going to teach you to fish. Go to hCaptcha’s website, then scroll to the footer. Click around on the about links. It’ll reveal their business model. This trick also works for other businesses and NGOs. Now, if we look at https://www.hcaptcha.com/labeling we can tell they make money by labeling data sets for a fee. So as a guess, there’s someone out there that needs to improve computer vision detection of t…

When they start doing captchas along the lines of "check all pictures of potential terrorists" we'll know they're training data sets for military drone manufacturers.

Every time I fail a captcha I just want to kill all humans

You're helping train self driving car models. https://www.ceros.com/inspire/originals/recaptcha-waymo-futu...

OP is talking about hCaptcha, not google's reCaptcha. Besides, reCaptcha is not being used for that anymore. They probably stopped doing that a while ago.
