The work [of software development] is becoming far easier (i.e. the tools we're using work at a higher level, more removed from machine, peripheral and operating system imperatives) than it was twenty years ago, and because of this, knowledge of the internals of a system may become less accessible. We may be able to dig deeper holes, but unless we know how to build taller ladders, we had best hope that it does not rain much.
