Thirty years ago I submitted my final year undergraduate project: a computer conferencing program for Unix workstations. Unlike the conferencing apps we’re all using today, thanks to Coronavirus, it didn’t include photos, audio, or video—
it was simply words typed onto a screen. However, it did have emojis as part of trying to handle the limitations of human communication via technology. Now, of course, I would have lots more data and theories to help me assess what those limitations are, thanks to the mobile and internet age.
