I agree with you, and yes, F# does help you write safer code. My main objection is with people claiming that NREs cannot happen in F#, which is simply incorrect - it sure happened to me when I was learning some F# and tried some interop (and you're not going out of your way in doing interop, using some external library or what have you). Which is fine I guess, but I think it's important to be clear about the benefits of the language when recommending it.
