It happens periodically. I had a job as a security guard years ago (circa 2008) and one of the older guys I worked with lost his job years before due to digital photography. There was no demand for people who can develop film anymore so he retrained to be armed security. Funny enough, developing film has become a niche market now so maybe he’s back to doing it on the side again.

Point is, specific jobs disappear but human labor is a very long way from becoming obsolete.
