No, unless you have some solid studies at hand that would clearly support your „hypothesis“, it is nothing more than a highly biased imputation.

Here is my antithesis: Elixir/Erlang doesn‘t sustain for a small mid-sized org in terms of building maintainable software. Elixir/Erlang requires more maintenance (higher learning curve -> much less clear code -> more bugs -> more developers needed).

Now does this sound like a valid hypothesis to you? Probably not, until I would be able to back my claim by solid numbers.
