I had a customer-facing programming job (something like a technical consultant). I had to speak English understandably -- even over the phone -- and be a polished, likeable, and competent representative for the company.<p>It&#x27;s hard to imagine how this could be done without &quot;flawed human judgement&quot;.<p>Some jobs might be form-filling or widget-building in a dark basement, and you might be able to get away with this. But a lot of jobs are not that.
