Gold has been used as a currency historically for many reasons. It's inert. It has a low melting point. It's malleable and easily divisible. It doesn't tarnish. A piece of gold from 2,000 years ago will be the same weight today as it was then. It also is attractive, which gives it value for jewelry. And, importantly, it's predictably rare and can be mined.

Today, it's also valuable for electronics. Its inability to tarnish makes it fantastic if you need a connection to be corrosion resistant.

There's a reason gold still holds its value even though it's not used for currency anymore.

Gold's value isn't tied to its usefulness. Based on statista, less than 7% of global gold use is for "technology". The rest of it goes to jewellery, investments and banks.

The quantity you need for gold to be as useful as it's going to be in whatever application short of aesthetic/monetary value is so low that it just doesn't make sense for its value to be tied to its actual use. So little gold is used for "real" applications that if that was driving its valuation , it'd be probably 10% as valuable as it is. That's what people mean when they say it isn't useful.
