AI Language Translation and Programming

I am sure that what I am about to discuss is not original.  Writing this is based on my eternal frustration with programming in so many languages over the years that it amazes me something has not been done about it.  Now, I imagine, it is being done, just not out in the open.  Let’s start with a simple image of the Google Translation Engine.

So, what is the big idea?  Seems to me this same mechanism can be used to translate any programming language into another almost instantly.  Now, wouldn’t that be great?
