I would have expected gold to be used more in the technology sector 
Discussion
It would if it was cheaper 😅.
Gold is seen as a last resort in technology. Material science continually finds alloys that compete with gold.
There are limited applications for gold.
If gold were priced as a nonmonetary commodity, it would be cheap enough to coat entire vehicles in it to fight corrosion.
Gold has great conductivity iirc, let's hope bitcoin solves this monetary premium problem
have also asked myself whether cheaper gold brings innovation
The illusion of scarcity.
the amount used on connectors and micro wires is miniscule... not even a microgram on a typical gold plated hdmi connector
