The thing is, what applies to you doesn't necessary apply to everybody. Somebody has to understand low level coding. Somebody has to be introduced to it without necessarily knowing going in that it will be a career path. Somebody will need to write compilers and reverse engineer and design CPUs. Just because a skill isn't valuable to you or those you know doesn't mean it isn't valuable to others, especially those who don't know enough yet to know that it might interest them.
