This is one of those stories, just like the SR-71 "ground speed check" story, that every single time I see it posted I just have to read the entire thing again. I love it.

All time great short story. Has shaped my world view since I first read it many years ago.

My favorite short story of all time. Between this and Deep Thought in HHGttG, I couldn’t believe the prescience when the bitter lesson was learned and LLMs and GPUs started eating the world.

Lots of good comments over the years -> https://hn.algolia.com/?q=%09Isaac+Asimov%3A+The+Last+Questi...

For a while I thought I really liked sci fi novels and short stories, and maybe that's somewhat true. But I've started wondering if maybe I just liked Asimov's writing in particular. Other writers in the genre are more hit or miss. Can anyone recommend other writers that are on his level?

I love this story. When I first read it online in college many years ago I was surprised, and disappointed, when I suddenly realized it was a short story. It's a great one to recommend to people.

A classic. It was dramatized by the Rochester NY, USA Museum of Science as a planetarium show, and I saw it there about 1974 with my father. Great times.

I wasn't expecting to find my favorite short-story on HN today! That's a pleasant surprise! This is how I started my journey in reading Isaac Asimov, I really recommend it!

One of my all-time favorites. Almost every time I'm involved in a conversation about books, I always mention this. It amazes me how many people have never heard of it.

okay so i'll be the sole commenter of: hex.ooo is an incredible domain name to me, maybe because i dig its UI, but certainly just in general didn't know about ooo, maybe because it's not available on namecheap!

>INSUFFICIENT DATA FOR MEANINGFUL ANSWER Boy, it sure would be nice if real LLMs were capable of giving an answer like that.

I remember the first time I heard this story. I was maybe 7 at a planetarium and they animated it with music little hand drawn starships and retro computers floating among the stars. They turned the stars all out for the final scene.

Somehow never read this one. But did write a short story ~20 years ago with a similar arc. I guess reading a lot of Asimov and Clarke and others will do that to you.

An absolute classic! Was just telling a buddy about this one the other day while talking about The Egg by Andy Weir (another short story I really enjoy). Every time I read this one, I get chills at the end. Asimov really was a master.

In the 80s, our local planetarium did a show based on this story. The executive director of the museum associated with the planetarium had a very nice deep voice and was the perfect narrator, though it gave the Cosmic AC a slight Texas accent.

> How may entropy be reversed? Considering AC could persist indefinitely in hyperspace while interacting with normal matter, the answer would appear to be "hyperspace", whatever that is.

I'm happy to see this short story posted here, it is one that I deeply loved when I was 14 or alike, and read it again multiple times. But I wonder: how did it survive in those sites without being shut down by the Asimov writings copyright holders? Given that the story is short and highly shared, it was just tolerated? EDIT: actually I see that the link historically posted here more often is now dead: multivax.com/last_question.html

And then read Asimov's The Last Answer, good dichotomy of stories.
