I used the dictionary definition, but I agree that there is not a great consensus around what remote actually means. Your definition seems to be in alignment with how computer science has traditionally used the word remote, seeing this from a networked computer perspective instead of a human perspective.

Which perhaps makes perfect sense if the work involves using a networked computer, but what about work that doesn't use networked computers? We also have trucks that allow coworkers to work at a distance from each other.

If that's your definition, then I have been working remotely since 2014 -- because that was the year my employer opened a second office, and many coworkers go to the closest office, not where the majority of their team is located.
