They have to be taken from odd angles. Otherwise, they'd match the data sets used to train object recognizers.

This is a losing race with neural nets. CAPTCHAs are running into the same problem that Yosemite park rangers report with "bear proof" trash cans and storage lockers: "There is considerable overlap between the smartest bears and the dumbest tourists."

Earlier quoted context omitted.

Being asked by a machine to prove that you are human is sometimes really humiliating, especially if you fail the captcha a few times in a row.

I understand why websites need to use captcha. I do not understand why websites that have user accounts cannot offer the option of 2FA TOTP, or even SMS login to avoid captcha. Hilton.com is a big annoyance.

I don't understand why they need it when they've already accepted and verified a login request, just need captcha to finish it off? (i.e. you don't get the captcha with bad creds)

I mean, maybe I can see/accept an argument for that. But when I have a recent order? When I'm logging in from the link you just emailed me?

> Part of it is the sheer hassle of repeatedly identifying objects — traffic lights, staircases, palm trees and buses — just so I can finish a web search. Does Google ask you to complete a CAPTCHA to run a web search? I've never experienced that - is that a thing?

I get these pretty often on Firefox Focus (Android), not because of any unusual searches (as far as I can tell)! It did at least push me to switch the default search to DDG.

I wish my life was so utterly without other problems that I could get this worked up about something so minor and meaningless.

yet it went viral, so apparently a lot of ppl find it interesting, and the traffic probably is an incentive for him to keep writing similar articles about seemingly mundane things. There is a huge online audience for mundane observations, as opposed to the always-on news cycle.

Several people mentioned ways you can trigger it using 'nonstandard' (by Google's expectation) methods. In my case I hit it with just regular Chrome whenever I start doing a few searches that use more than basic keywords (so stuff that uses the prefixes like filetype: or parenthesis for logic)

I'd say it's because the North America, car-dominated, strip-mall-and-stroad landscape is depressing as hell. Open a map and drop yourself somewhere in Europe. I just did, and I feel like identifying crosswalks in a photo like this wouldn't be depressing at all:

> Google’s CAPTCHA images are frequently grainy and badly focused. This is likely because, as Vox points out, Google has gone through most of the easy visual-recognition training cases, where the pictures were clear and sharp. Now they’re stuck with the hard stuff, which tend to be pictures of terrible quality. While this is true, I think some of the artifacts in the accompanying example are added by Google as a sort…

It’s not just that — google wants its own models to be resilient in the face of noisy data. (You’ve probably see examples where a cat is classified as a mountain or something ridiculous due to the addition of precisely crafted noise.) The best way to achieve that resilience is to simply train the models with noisy data; part of the learning process will then be learning to ignore the noise.

For me a part of the melancholy feeling comes from the indignity of being forced to prove I'm human, and then the frustration at this stupid world we've created which requires me to do so which immediately follows the indignity. A website with captchas is like a retail store with metal detectors; it's not somewhere I feel welcome.

But metal detectors don't block your way for 20 seconds and they don't ever put you into an eternal loop of scanning again and again until you just give up and decide to live without.

They do delay customers by 20 seconds, because if we’re carrying metal then we’ve got to be inspected by security.

For me this effect is significantly compounded by not being from the US / North America. This has come up on HN before (e.g. https://news.ycombinator.com/item?id=25226805 ) but it still strikes me as so odd that you need quite a bit of USA cultural / vernacular knowledge to navigate the internet anywhere in the world (or at least English speaking sites?). What a strange view into another country to see each day!

Seems like CAPTCHAs shown to users outside the UA should show local road images because locals know best how to identify objects on their roads. Perhaps Google is prioritizing the autonomous vehicle market in the US for now.

In a quite a few instances, I find it flattering, because it implies "we haven't sucked enough data on you already to know if you are a human, so we need to be sure."
