Ask HN: Why does Cloudflare/hCaptcha care so much about buses, boats and trains?

#22It'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.

#23First, 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…
Makes sense since other than the ones mentioned I received a lot of crosswalks, traffic lights and bicycles.
It's odd that it never asks for pedestrians.

#24I 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 see a bus, a boat, a bicycle, or a crosswalk, this may be why.

#25Earlier quoted context omitted.
Yes but if you make a mistake the capcha fails, hence they are already labeled.
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.

I recall some controversy a couple years ago over suspicions that defense contractors were using them to train weapons systems. A few people got captchas asking them to identify helicopters.

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.

I've dreamt of a captcha to prove that one is a robot, such as: solve this complex mathematical equation in 15ms.
