Reasonably good presentation, but this stuck out at me:
> One team that started with Erlang and moved to Java so they could find programmers. Think about those scenarios.
If the people you are hiring can't pick up Erlang in a couple of weeks of being on the job when they are doing that full time, with colleagues around who already know Erlang to help them, you are hiring the wrong sorts of people. Same goes for any other language/technology stack.
