Arguably this might be true, however if you add another requirement to the list Joe posted it isn't. Cross platform code is important to many people. I work on large scale, performance intensive, cross platform applications. Microsoft tells me I should be doing everything in C#. Apple tells me I should be doing everything in Objective C. I just get on with it and use something that works. A language that gives me the ability to combine high level design with low level efficiency and run on multiple platforms.

I often use a paraphrase of the Winston Churchill quote as well. There are probably many better languages for many other applications, however for high performance, cross platform large scale apps C++ is still the only game in town.

Joe's point that all the complexities have reasons behind them is a really good one. I'd suggest reading Stroustrup's "The Design and Evolution of C++" for more information.
