There is none.
A programming language is a tool.
Similarly, a saw is a tool. By comparision, you are looking for a saw that only the best carpenters use, because they're super productive with it and can make the neatest cuts -- but one which most woodworkers don't like, because it's hard to use and not very useful to them, because they need a saw that other carpenters like, so they can all work together regarding technique.
When you select a language, you are selecting a tool. You should learn which tools are most suitable for what purposes, and select appropriately to your specific problem.
Edit:
Most of your update seems to agree with my point. I disagree, though, with this:
>> A programming language is more than a tool. Programming is like poetry.
No, I don't think so. Poetry cannot be quantified, is ambiguous in the general case, and, as such, is incompatible with computation.
>> It's not like choosing a tool
It is _absolutely_ like choosing a tool.
I presume your hypothetical, multilingual poet would select the language in which his thoughts could best be expressed, and in the tone most conducive to expressing the representation of his feelings.
Were I to grant the similarity required for the argument above, it would beg the question: what would be the most "elite" language for poets?
Who's the most elite? Multiple, competing, objectives don't leave room for one "best" programmer or tool in every situation.
There's this old adage originating from Parker Hannifin Corporation:
"Pick two: good, fast, cheap".
Let's assume Joe is a programmer who is exceptionally fast and cheap.
I think you'll agree that you don't want him writing the software for your cardiopulmonary bypass machine, but for writing some throwaway prototype, he's clearly the best choice.
For the CBP machine, you might seriously consider picking "good" _twice_, because equipment failure in this case is completely unacceptable.
The tool must be suited with the problem. It doesn't have to do with which is objectively the best in every situation, because that doesn't exist. Each language is consciously and obviously designed for different purposes --- how can you seriously claim that the design goal of each is irrelevant!?
Edit:
I was going to bring up the language, but decided against it. I'll keep it short this time:
Points:
--- All languages are equivalent
--- The only thing special about Lisp is it's macro system, which allows defining new syntax easily.
--- Macros (in this sense) are not needed to define new syntax: it's hard - but write an interpreter.
--- New syntax is not required to define DSLs. All abstraction contributes to a language.
--- Lisp macros are hard to read and prone to subtle bugs: have you ever debugged an anaphor you didn't expect to be there? Lisp's syntactic duality trades simplicity for versatility which isn't usually required - and complexity is bad.
--- Forcing everyone to read _a new language_ is hard enough. Throw in new syntax and the complex (untested, immature) metacode defining that syntax and things get complicated and buggy. This is bad.
--- A language serves as a starting point for solving problems, but all (computable) problems can be solved by any TE language. Pick the one which gets you closest, the fastest.
--- For most problems, Lisp is a harder than necessary choice. You are not the only programmer.
