There's a big difference between HTTP, Apache, and ORMs. People not understanding why they're different is what sinks companies all the time. Using any abstraction is a gamble that it doesn't leak before you have the resources to fix it. HTTP is a terrible comparison because in almost every domain you will either make millions or (far more likely) fail for other reasons before you need to understand how TCP/IP works. I bet there's loads of companies that have died a slow death, releasing everything a month later than they want to, because the back-end developers aren't comfortable with whatever the stack of the day is and they were too busy learning yesterday's stack of the day instead of the intricacies of the language they're working with, or the standard library.
