F# code is much more reliable and requires much less people to write. Isn't this good for business?

The only problem with F# is it's not always immediately readable to those who are not familiar with it (so it's harder to find the people to hire), isn't it?

I just wonder how much harder it is to teach a random person (without even a rudimentary programming skill) to code F# than to teach them C#.
