Computers were originally the employees doing scientific or financial computations. Then electronic computers took over some of their job."Computers" were just a made up term at some point too. As was desktop computing. Etc.
What Apple calls Spatial Computing is what is normally called VR and MR/XR. Apple also didn’t invent the term, it has been used since the early 90s (https://en.wikipedia.org/wiki/Spatial_computing#History), though it never quite caught on. IMO it’s unlikely to catch on now as well.
