While I agree that different langauges promote different solutions (otherwise we wouldn't bother making new programming languages!), I'm sorry but it's just false that a statically language without generics can be sufficiently expressive.
Generics are necessary to move information of different shapes through a function without loss of fidelity. Without generics, there is an artificial trade off between the variety of the inputs that can be consumed, and the richness of the output that is produced.
