"Multithreaded programming is still one of the most problematic activities even for senior programmers, to this day. Multithreading bugs get written and fixed every day."

Strongly disagree. I am going to claim that threads / locking are not hard to write if one has at least a bit of common sense and discipline. Problem is that we have hobbyists without any trace of knowledge on how computers work producing commercial software.

Goes like this: I do not want to deal with memory management - it is too hard, I do not want to think about types - my poor brain can not comprehend those, pointers - OMG what are those beasts, threads and locking - gonna commit Seppuku. I will advise those to come to a logical conclusion: programming is frigging hard when one wants to produce a decent product rather then buggy POS. No matter how many concepts the language hides / converts to something else there will be always something else they will not be able to wrap their mind around. So how about trying gardening instead
