How often do people jump into javascript coding without having the faintest idea of how a CPU or anything else works? When high-level facilities are made available, there are always going to be people who go to the high-level facility without having any understanding of the actual consequences of what they are doing. I'd recommend the software folks who want to get into hardware to check out the book 'Elements of Computing Systems' and the NAND2Tetris project that its based on. Its quite easy to follow along with building your own quasi-HDL things run in a simulator (with no generative for-loop stuff, you have a clock line and you use it), then build up from there to put together a CPU, memory, develop a basic OS, implement a programming language, and eventually play a game of Tetris! All with nothing but NAND gates and the convenience of being able to 'use' those tons of gates without actually having to deal with them physically.
