=== A Hard Truth ===
'''''No one who isn't already a seasoned developer with years of experience in several languages and environments should even be considering OS Dev yet. A decade of programming, including a few years of low-level coding in assembly language and/or a systems language such as C, is pretty much the minimum necessary to even understand the topic well enough to work in it.'''''
What's more, this is growing ever more true by the year, as the number of different 'standards', computer and mobile device models, peripherals, and design concepts continues to expand.
Line 21:
It was one thing for someone like Dennis Ritchie, Richard Greenblatt, Gary Kildall, or Steve Wozniak to write a simple OS for hardware which was relatively straight-forward in comparison to current machines, which they already knew intimately, and which had no standards specifications to adhere to or existing cruft to maintain backwards compatibility with. This is no longer true on current-generation stock hardware. Furthermore, each of them was already a seasoned engineer who had already done years of systems programming. Even then, they only provided the foundations for the systems; the bulk of the work was done by small armies of subordinate developers after the nucleus of the system - the kernel, in modern jargon - was in place.
There are exceptions to this rule, but not many; don't expect yourself to be that one in a thousand. If you think you are, read up on the [https://en.wikipedia.org/wiki/Dunning%E2%80%93Kruger_effect Dunning-Kruger Effect] and consider the matter again.
Oh, and for the record, Linus Torvalds wasn't quite one of them - he was a graduate student when he wrote the Linux kernel, and had been coding in C for years. While he was well short of that ten year mark, as a grad student who had turned his hobby into his master's thesis, he had more time on his hands to work on the project than most people would. In any case, the 'Linux 0.0.1' release he famously posted to USENET in 1991 was little more than a round-robin scheduler, nowhere close to a full system. Getting to that point took him a year. Get the picture?
