I love the implicit "answer this right or we'll drive a robot over a stranger someday" part of the whole prove-you're-a-human captcha experience.
@mhoye This joke (which I like, hihi) is grounded on the assumption of a kind of conspiracy about #capchas. Is there any proof of this #conspiracy?

@Depemig It's not a conspiracy at all. "CAPTCHA" stands for "Completely Automated Public Turing test to tell Computers and Humans Apart". It was born at Carnegie-Mellon in the early 2000s and Google's been using it to train image recognition algorithms, digitize books, all sorts of things since 2012 or so.

CAPTCHA: The story behind those squiggly computer letters

If you use the Web, you have probably encountered an annoying invention called a CAPTCHA.

@mhoye @Depemig
I’m not sure there’s a conspiracy; CAPTCHAs are definitely being used to train self-driving cars

Do you know you are training Google self-driving cars so they don’t kill people? Yes, by solving captcha

Every time you solve Google– supplied Captcha — and Google supplies this Captcha on thousands of popular websites — you teach Google’s driverless cars. Of course, you don&#8…

Thanks for all of your links. Appreciated. I really thought this was nonsense.

Maybe, I simply couldn't believe detecting hydrants is such a challenging job for self-driving cars! ;)

@mhoye

That, or Harrison Ford shows up to 'Retire' you for a wrong answer.

@mhoye @molly0xfff Brain is so bad today and assumptions of tech companies being evil, that I read crosswalks as Swastika.
@mhoye imagine one day seeing yourself in a captcha like this....
@mhoye these always fail to recognise me as a human being even when I try, so I stopped trying.

@mhoye

I'm looking, but no square shows a 'cross walk'.

Shouldn't I be able to see Kamala Harris walking off-stage after having given her most gracious concession speech?

Perhaps I should try looking for a burdened messiah, walking up the hill to Golgotha?

I might try looking for crabs, but I think their gait is more of a 'side step' rather than any type of 'cross walk'.

Tell ya what, I'm going to put my glasses on, re-read the instructions, and get back to you.

@mhoye Someday? It has already happened in Arizona.
@mhoye They made me click-work on 10 of those today for a single login 😡
@mhoye I recommend answering these wrong a few times until it falls back to giving you an object classification captcha that you're comfortable training. Time consuming. Sucks. But I feel better sorting animals.

@mhoye I also love that we’ve reached the point where you can answer these correctly and sometimes have the machine tell you you’re wrong. (E.g. Unmarked crosswalks are a thing, despite what the machine says).

It’s just a wonderful microcosm of the world when the machine trumps your human judgement, and you have to knowingly answer wrong to pass the gate.

@mhoye Two squares that contain bits of visible crosswalk are primarily taken up by a person's head and torso. What's the right answer?
@SoonRaccoon Declining to participate.
@SoonRaccoon @mhoye good question, I always fail these things, time after time, probably for thinking about such issues. Is the post holding up a traffic light part of the traffic light?

"Our investigation concluded that the driverless vehicle could not identify the pedestrian crossing due its vision being obscured by the cyclist and thus did not slow down or change course, resulting in a collision. We deem the accident to be the fault of the cyclist."

@mhoye what’s always confused me about these CAPTCHAs is that they already know if you’ve clicked the wrong square. If they already know, what’s the point of asking me to verify the images?

I guess it increases the verification of existing training data? It’s just weird. Half the time, squares feel ambiguous, anyway.

@deadsuperhero You're never the only person seeing the image. The idea is that the earliest people seeing an image are autofailed to another one, but the participation data is kept. Over time, the collected answers normalize to correctness. That's what the learning process is about.
@mhoye makes sense, thanks for the explanation!
@deadsuperhero You can read about the research behind the whole exercise here: https://phys.org/news/2012-06-captcha-story-squiggly-letters.html - Captcha - formerly CAPTCHA - is short for "Completely Automated Public Turing test to tell Computers and Humans Apart."
