Performance yes, there is always more power as long as the bank account is full, and even then it isn't enough when working at scale.

The amount of histories of porting code prove otherwise.

Note I am not pushing away dynamic languages, only those that don't have a JIT/AOT as part of their canonical implementation.

Common Lisp, Julia, JavaScript, PHP (7 and later) are all invited to the party.

Meanwhile maybe JRuby or PyPy will eventually get more community love, instead of being the black swans.
