One issue with egui and shoving the whole page into a canvas element is accessibility -- having just a canvas element is a screen reader's worst nightmare
We can change the definition of "future-proof" -- your cable was future proofed in that if you were using it for hundreds of years, it wouldn't require any maintenance and if the age of wireless tech never came, your cables would be relevant
Extreme example: not future-proofing cables would be like laying them out above ground where the weather/ elements will destroy them before a year's end
But agreed that buying for your immediate need, with a little bit of futuresight is helpful
