I doubt that manual typewriters changed all that much between 1900 and 1980, aprt from incremental improvements. However, technology then produced something better and they were then superceded completely. I believe that something similar will at some point happen with commercial air travel. Do I think we will be still flying in subsonic aircraft similar to what we have now in 20 years time? Yes. Do I think we will e still flying in subsonic aircraft similar to what we have now in 50 years time? Maybe. Do I think we will be still flying in subsonic aircraft similar to what we have now in 100 years time.
