Will high latency due to distance ever come to an end?

No matter how fast my internet connection is, there will always be a delay between two network nodes separated by huge distances.

South America - Europe, about 250ms

South America - Asia - 350-400ms

Will this ever come to an end?

I know every node that exists between two points add some delay, thats why in the end we have high latencies between two very distant places.

What phisical changes would be necessary? 100% fiber optics communication? I heard even fiber optics communication degrades at some point.

Thanks
