I think more people need to have a kernel hacker mindset. We are getting to the point where everyone is working so high level that they just assume you can swap out the Distro/Kernel/Arch and it will not only "just work" but will work exactly the same was as your home system. While your simple applications (not attempting to optimize or really push the limits of your system) you might not run into issues initially but when you try push things you'll inevitably run into the problem. The fact that we're talking about ARM makes this even more important. You're having to compete against x86, which requires increased core counts, and a lot more optimization and potentially even redesigns of your software to make your higher level environment to be perceived equal to x86. Businesses will need this, your boss will ask if ARM is as fast as x86 and they won't care to quibble about technological differences if you can't just get the same output speeds as their old, trusted hardware. There is only so much your language can do to cover your butt. At some point you'll have to be aware of your environment to compete.
