if they used static types it would be 100%

statically typed languages are to be seen as safer than their dynamic counterparts. While this might be true when comparing with many dynamic languages, Erlang begs to differ and certainly has a track record to prove it. The best example is the often reported nine nines (99.9999999%) of availability offered on the Ericsson AXD 301 ATM switches, consisting of over 1 million lines of Erlang code

i consider static typing cute, like scheme .. and totally useless for real world. kinda like walking barefoot. that should be what everyone does, it is healthier, but then you have people who are busy farming and what not to make you food, and put rocks on the road which sucks to walk on.
i'm the farmer, you're the person in the rocking chair complaining about blisters.
