This question made me conscious of the fact that the icons computer/smartphone and many web interfaces use are a metaphor for the way in which the industry has designed computers for a consumer market. That is, they are to be used to digitize and simulate old media.
For example, the use of the now-obsolete floppy disk to represent “save?”
The way this question is asked is interesting and encouraging. These icons no longer make sense to modern users. Another interesting question is what should replace them? However, without powerful outlooks, I suspect it’s going to be difficult to come up with anything that really captures the power of this medium that is computing, and we’ll just use the default of ourselves as metaphors.
