Voyager 1 & 2 is one of my favourite human science achievements, not even so much from technology standpoint, as it's relatively simple compared to what we have now (although that's one of the charms), but just the fact that it's so far away, it still more or less works long after the scheduled mission end time, we can communicate with it and despite all the modern technology progress, it would take decades to catch up. Absolutely amazing and inspiring!

A large amount of Voyager 1 & 2 's success isn't just technological it is the ability to take advantage of a specific planetary alignment for a gravity assist [1] that can only occur every 175 years [2] .

Don't forget that the mission planners figured out the "Grand Tour", calculating orbits and trajectories to slingshot around the Solar System. All with 1960s technology.

Yes, yes! I got really into the Voyager-inspiration vibes for a while and wrote this little short story about a secret "Voyager 3" mission - thought you might enjoy it: https://f52.charlieharrington.com/stories/voyager-3/

Voyager, Apollo, and Hubble. Everything else NASA has done is a distant 4th place. And it's not like 4th place is trash, it's just that the big 3 are just so impressive.

Could you elaborate on this?

They are dangerous and reckless. They were also done in the name of humanity, but without humanity’s consent.

I despise the naive scientists who did them as much as those who brought the damocletian sword of nuclear weapons on us.
