The complaint is that writing GUI apps is painful not that it's impossible. In particular, when compared to other platforms, windows has had 30 years, several frameworks, market dominance, and they all still end up getting a D- for one reason or another.
Long compile times are annoying and affect productivity. Some people are really sensitive to this type of disruption and it gets very difficult to stay in flow when the only thing you can do is sit and stare at a progress bar. This is particularly offensive to C# developers.
Take your elitist attitude and your gigantic C++ monstrosity elsewhere. Tell me you haven't used a modern JIT language without telling me you're a scrub. Jesus.
Ah, yes, I must be a C++ advocate who has never used a “modern JIT language.” I’ve actually been using them since before the term “JIT” was in common use, just like I used C++ before it had templates or exceptions.
Incremental compile time on the order of a minute should not a big deal in a project. How would someone who can’t handle that have fared in our industry 30 years ago? Yes, faster compiles are nice, but they aren’t what will ultimately limit you unless you have an untreated medical condition.
