问HN：为什么在近20年里，手机打字没有改善？
今天在iPhone上打字的错误率和2007年手机发布时一样高。<p>下一代的预测输入技术在日常使用中已经在很大程度上解决了这个问题。<p>如果结合滑动输入和更现代的预测模型，我们就能够在不看屏幕的情况下单手打字，并且达到完美的准确性。<p>我们现在拥有这样的技术，但出于某种原因，没有人在使用它。为什么呢？

Typing on an iPhone today is just as error-prone as it was when the phone launched in 2007.<p>Next token predictors have largely solved this for day-to-day use.<p>Swipe + a more modern prediction model would mean we'd be able to type one-handed without looking at the screen at all, and have perfect accuracy.<p>We have the tech today. For whatever reason, nobody is using it. Why?
