Ask HN: Have you personally witnessed a machine replace a human job?

I was recently inspired by this NYT article: https://www.nytimes.com/2017/04/28/technology/meet-the-people-who-train-the-robots-to-do-their-own-jobs.html?_r=0

What are some of examples of your own experiences where you have seen AI and Automation replacing human jobs?

In my startup a big component of what we do is label recognition which is outsourced to a 3rd party Image Recognition as a Service provider. There are a team of people transcribing when the recognition has failed or been rejected, but over time as the vendor's service gets better and better we will be able to do transcription with less people.
