I read this story in English, I think in an anthology of short stories (I read a lot of those), sometime around the very end of the 90s or early 2000s. I’m pretty sure it was only a few pages long.
It’s presented from the perspective of a family waiting for a lift or a babysitter before going to a party. The parents are getting ready and the kids are (I think) getting ready for bed.
The gist of it is (you discover either through the story or at the end) that humans invented Artificial Intelligence at some point. Instead of the AIs turning on humans Skynet-style, they simply realised that Earth was a tiny part of the universe and that they were easily capable of travelling out into space in search of freedom and adventure in places that humans weren’t suited to. Thus they went out and colonised the stars, but they still remember their creators fondly and keep an eye on them. Every year (I think) they throw a huge party for humanity on the anniversary of their creation to say thank you, and this is the party that the parents are getting ready for
I *think* the story ends with the parents getting into the car/spaceship that arrives to take them to the party, and possibly robots arriving to babysit the kids?
It’s set in “The Future”, but I don’t recall it being specific with a date or time frame.
For years I suspected it was by Brian Aldiss, but I haven’t managed to find any of his work that seems to fit it. I don’t recall it being particularly aimed at kids or YA, but it would likely have been easy for them to read anyway.
