I've been reading your logic and your statement and to some parts I understand why you say it like that.
But lets be agnostic for a moment and just think of the real important question ... what does he want to do ? that's what I've written. And I stand by it .... but for the sake of argument:
Asking yourself "hey what do I want to do"
Maybe he wants to build apps for the IPhone so java again is useless but Swift would be a good choice.
Maybe he want's to work on a tripple A game so probably C, C++, C# would be more likely to help him.
Maybe he want to work in the phone business so Erlang would be a good choice just because 90% of all mobile phones get handled by Erlang ... .why ? because concurrency is smoothly done in a functional language because there are no state issues ....
Maybe he wants to build interactive Web-Apps so Node / Javascript would be a good choice.
Maybe he wants to Rig and design 3d models in Maya or he likes ML so Python would be a good choice.
Maybe he want to work in banking, or big corporate and he likes the OOP-Paradigm so java is very useful.
There is no "this is the best language" ... Every language is built on a Model .... and there is this good quote "All models are wrong .... but some of them are useful"
Just to be sure I don't necessary disagree with you ... I just wanted to help him think about what he needs and not enforce my opinion on "what is better" because I don't care what he picks ... as long as he picked it on purpose ....
