It's tricky and there is no one-language-to-rule-them-all because they have up- and downsides. C++ has the advantage of an incredible amount of code written in over the years that mostly works. It also executes fast. It's also easy to find developers for it. With the new addons to the specification it's even possible to write readable code with it.. However, it has a stupidly long, verbose and feature creepy standard (well over 1000 pages), which results in no developer reading it. Because of it's design, compilation times tend to take long (as a ridiculous amount of headers are included even in the most simple applications). Go is pretty much the opposite. It has a lean and readable spec (on purpose) and a fairly common canonical syntax without much discussion about it. Because it's relatively new, there is not much written in it however. It has some specific strengths, like a concurrency implementation that abstracts most of the process/thread/mutex stuff. With this, it does appeal to new projects that don't depend on libraries written in other languages. There is no point in porting multi-million SLOC applications to Go though, as that would be incredibly time-consuming. It has the potential to surpass C++ in a few decades though, as it operates in the same domain (systems programming). Python is a versatile scripting language. It has nice syntax and is incredibly flexible at manipulating data. Add to it the well documented, feature-rich standard library. With it you can evaluate data with incredible flexibility and it has a fairly complete feature set for general programming tasks that span multiple OSs. The downside is that it's slow in execution and needs the interpreter along the scripts. Especially for smaller tasks and simple automation it is the first choice however because of it's small footprint in constraints (you can just edit and drop a scriptfile anywhere on a Linux system and it works). Java.. I'm not entirely sure what Java does well. I hear praise for the JVM, but generally I get the impression that it is plagued by legal issues, alien looking GUI tools, more than verbose syntax and it also has a stupidly long specification (almost half of C++'s). Maybe someone can shed light on this one. Tools maybe?
