I suspect there are not many technologies that have had a relatively short life span. For me, these include the overhead projector. This is a device on which transparent transparencies were placed. What was written or drawn with matching pens was then projected onto a surface. Both here and with slides, what is relatively small in the original is massively enlarged by projection. That's what it's supposed to do, so that you can recognise it as well as possible. In psychology, too, we know a phenomenon called projection: one projects into or onto others what one would like to see there or what one does not see in oneself and then images onto others. This in itself is not really good. But it becomes bad because, as with the overhead projector, the magnification or exaggeration effect occurs. This is harmful in relationships and often distorts the truth. Therefore, caution is advised against such projections.
I wish you an extraordinary day!
