I totally agree with this article, except:

"That’s what tax preparers are – they use the exact same software that anyone can use at home, but they allow you to talk to a human instead of learning the software"

IMHO this is one of those edge cases where software might simplify the process 99 times out of 100, but a skilled/experienced human may help avoid uncommon but costly mistakes. There is enough nuance and vagueness in taxes that it pays to have a human look over your numbers -- even if they use software to do it.
