Personally, I don't see that title as rude. It's a perfectly legitimate question!
People will find different things fun, and for different reasons. The things that people find fun in Star Wars are probably very different from the things that people find fun in Star Trek (because they are different series).
Exploring those differences can lead to a greater appreciation of both series, and it can help people to choose which series they like.
For example, if I know my friend's tastes in movies, I can recommend a movie based upon that. Or if I was deciding whether to watch Star Wars or Star Trek, I could make that choice based upon an understanding of the differences.
I think the same thing applies to Ada vs Rust: they are different languages, with different goals. Understanding those differences can help you to appreciate them, and help you to choose which language to use for which task.
