I get why it exists, but we also have to be honest with ourselves and admit that there is a massive problem in communicating without assumption of prior knowledge/experience. The tech world is particularly guilty of this, with veterans having forgotten that there was a time when they didn't know what they know, and lacking any patience to adequately help those seeking understanding. To add to the issue, the Internet proper is so noisy with partial or broken information that the task of finding the correct information is far more daunting than it was 20 years ago when I started learning.

We need to give newcomers a break and answer their questions well, and discuss to promote understanding, instead of swatting at them with our canes. The only way knowledge passes to the next generation of thinkers and tinkers is if we fuel that curiousity.
