And Voyager 1, the furthest man made object from Earth, has been travelling for 45 years and is still less than 10% of that distance

Voyager 1 was launched 74 years after we invented powered flight. That's a single generation.

Cosmologically the rate of progress is scarily fast. It took billions of generations to get from mammal to human. It took trillions of generations to get from multicellular life to mammals. It took billions of trillions of generations to get from single cell to multicellular.

It took one generation to go from land based organism to putting objects so far away from land they are measured in the speed of causality. The highest speed achievable.

Voyager 1 (61,000 km/hr) - 1977
New Horizons (84,000 km/hr) - 2006

Though by the 21st century, we aren't going all that much faster.

Parker Solar Probe 690,000 km/hr

These craft go the speed they need to go to achieve their mission goals.

We can go much faster than Voyager if we choose to.

Yeah, but 450 years actually seems like some humans can do unlike the bajillion years it would take us to get anywhere.
