Well, I don’t live in Silicon Valley, and as a result, the company I work for is not a Silicon Valley company. If I am going to convince the management to invest in Elixir, I need to be able to answer questions like this. Pretty much everyone I have spoken to about Elixir, inevitably brings up this point.
I don't understand why you make the distinction between Silicon Valley and not Silicon Valley because where something is done makes absolutely zero difference as to if it's a good idea to use software or not.
If there was a text editor that you thought was good but was only in use in Silicon Valley would you still recommend it? I've never ever in my life discounted a piece of software because it was only in use in Silicon Valley.
Maybe you could expand on the argument because I don't understand it clearly!
