combined with its relative non-reactivity make it a great choice in fact gold is very popular for what's called wire bonding the act of connecting a semiconductor die to the package that holds it like what you might see on your typical desktop CPU gold can carry a lot of heat without melting or cracking so it won't hurt your performance just because it's inside the hot environment of your CPU package this is especially important in automotive applications our cars are becoming packed with more and more electronics some of which control critical systems you don't want an autonomous driving feature to fail when you're going down the highway at 70 miles an hour so gold is used because it's resistant to the thermal and environmental hazards your car can encounter while it's in motion additionally gold is very easy for modern manufacturing devices to bond quickly so it allows chips to roll off the line in large numbers but gold is also useful for applications you might actually see every day you know how more premium cables are sold with gold plated connectors although this doesn't do anything to make your signal faster it does keep the connector from wearing down as quickly
