You're naming and lambasting multiple different technologies and their communities without justifying why they are so bad. Few people use C without knowing about the threat of buffer overflows or invalid pointer dereferences, and C can be used productively in spite of these obvious flaws. Instead of trying to drive people away from what they do, if you seek understanding then you should allow others to justify their reasons. If you only test your understanding against your understanding, you're not making an assessment at all. You can find and talk to many smart people here and elsewhere, if you so desire.
