When I was young I imagined that when I'll be an advanced programming/CS student I would learn advanced stuff like self-modifying code. Too bad real life is not that exciting...

You can get a job in compilers if you want. Message me via my profile if you don't know where to start.

If you’re interested, JIT compilers or malware reversing is a “real” place where this knowledge is useful.

Also don't forget binary translation which basically is assembly level JIT. Although static binary translation is a thing but has limitations.
