Has anyone used assembly recently?

Question

My 13-year-old has been experimenting with reverse engineering and modifying Android games. He's fascinated by Smali, can write in it directly, and uses Apktool to repackage the APK.He's now interested in learning assembly language.Has anyone here worked with assembly in the past 5-10 years?Could you share your experiences, including why you used it and what you accomplished?

Here is something I did that your son might be interested in. It is simply Hello World, but done 6 different ways using ARM assembly language.

I did a lot of Assembly language programming in the 90's, on Intel, but I haven't really since then. Still a fan of it though.
The best thing I got out of it was a super-deep understanding of how computers actually work (versus what it seems like they do if you program with higher level languages.)
