Depends. Any programming language is suitable, given the correct 
circumstances. And what application? Developer needs? Business 
needs? Say if you want to run rendering via photon-tracing in a 
cloud, obviously for performance you'd go for a language that 
executes in native code at some level. Or you want development 
speed. And so on, and so forth, yada yada yada... We can have a 
1000-post thread and there will be no clear position. I can sell 
you A and then switch and sell you B and both positions would be 
strong. What matters more is your analysis given your 
specifications. Is this for business or for a dissertation?
