One day, humanity may progress so much that it will be reasonable for us to send missions to retrieve these craft, to be reunited with humanity.

It depends. The voyagers were able to utilize several grav-assists in a rare planetary alignment, giving them speeds far beyond what humans could send them at. That alignment won’t happen again for a really long time. So, we have to make something that artificially thrusts the objects into higher velocity. Nuclear & ion thrusters are a possibility.

Not likely at our current technological stage. Nor are we looking. That’s changing, though. There are things like “The Galileo Project” coming into existence where the project aims to search for relics of otherworldly civilizations in our solar system.

@abelis644 They are traveling insanely slow compared to the speed of light. If humanity can achieve even 10% the speed of light. Catching up to them won’t be a problem at all. Perhaps future humanity decides it doesn’t want to broadcast its existence to the galaxy. Perhaps we’re living through Dark Forest Theory as an explanation to the Fermi Paradox. If that’s the case, humanity has every incentive to retrieve them. There’s plenty of other reasons to want to retrieve them, under other scenarios as well. Simplest one: It would be a milestone for humanity. It would signify that we could also catch up to ʻOumuamua, and answer what it is once and for all.

We’ll likely be type 2 in 3,000 years, if we survive. Type 3, we’re looking at an aggressive estimate of 2-5 million years. Likely longer to become a full type 3. Unless we make extreme paradigm shifts in our understanding of physics.
