强烈推荐vowelless · 原文
说明
这是2011年由TED发布的一部演讲，主题归在Futurism & technology and society。它讲的是crowdsourcing and human computation这一支里的具体问题，而不是把整个领域扫一遍。适合按兴趣直接看、不打算先补课的人。内容上可以概括成：Luis von Ahn, creator of CAPTCHA and reCAPTCHA, explains how small contributions from many people online can digitize books. He then introduces Duolingo as a way to translate the web while people learn languages.这些读者给出的理由，核心是：HN commenters recommend it as the clearest account of human computation and games with a purpose, straight from the inventor.讲法不绑某一条新闻，过几年仍然可以当材料看。从2012年到2022年，有4位不同的读者在4个不同月份把它推荐出来，其中明确叫别人去看的有2次。适合一次性看完。讲者把一个判断讲透，演示是在给这个判断配例子。如果已经会了基本定义，就把注意力放在它怎么把crowdsourcing and human computation变成能跟着复述的例子。
