This approach was used by Google to identify house numbers for Google Street View, and nowadays Google also uses CAPTCHAs to identify street signs and objects in pictures. This might be a reasonable way to help improve the performance of the AI in a self-driving car that responds to video input, by reviewing images it might encounter and flagging road signs, etc. that it should respond to. |
− | However, the temptation might be to simply sidestep the hard problem of AI by having all instances 'solved' by "offloading [the] work onto random strangers" through CAPTCHAs. For example, this has been used to defeat CAPTCHAs themselves; people were asked to solve CAPTCHAs to unlock pornographic images in a computer game, while the solution for the CAPTCHA was relayed to a server belonging to cybercriminals. (See [http://news.bbc.co.uk/2/hi/technology/7067962.stm PC stripper helps spam to spread] and [https://doi.org/10.1016/S1353-4858(08)70036-9 Humans + porn = solved | + | However, the temptation might be to simply sidestep the hard problem of AI by having all instances 'solved' by "offloading [the] work onto random strangers" through CAPTCHAs.

− | Alarmingly, the developers of this '{{w|Self-driving car|self driving}}' car seem to have gone for the lazy approach. Instead of teaching an AI, the CAPTCHA answer is used in real time to check whether the "self-driving" car is about to arrive at an intersection with a stop sign. This information is pretty critical, as failing to mark the stop could cause an accident. The user is unlikely to respond to the CAPTCHA in time to avert disaster, not to mention that any interruption to the car's internet connection could prove fatal.

Other synchronous decision systems which actually exist are political voting and money as a token of the exchange value of trade. |
The title text explains that this method could be called "crowdsourced steering", {{w|crowdsourcing}} meaning sending the data on the internet to let several users provide their ideas and input on a problem. People would naturally suspect that this is considerably less safe than a car which is actually capable of self-driving; if the internet can barely [[1333: First Date|collectively steer a videogame character]], what chance do they have steering an actual, physical vehicle? | The title text explains that this method could be called "crowdsourced steering", {{w|crowdsourcing}} meaning sending the data on the internet to let several users provide their ideas and input on a problem.
