The quarter inch jack was first used for phone switchboards in about 1877, or 147 years ago.
The smaller 3.5mm is from the 1950s when radios started to become portable.

For my voting in the EU parliament, I entered a school (junior education) while they were having class, and I noticed that even the very young kids were behind laptops. This is a massive difference compared to my childhood when only the final junior years were allowed to use calculators.
I have no criticism (tools are tools, whether they are an abacus or a laptop), but I am surprised at how much progress humanity has made. 🤯
