Agreed, interns are extremely expensive and anyone who thinks that they are cheap labor is not aware of the day to day details. Only reason to ever have interns is if you want to give back to the community and grow your senior talent. You might end up with some loyal developers that know your stack, but I wouldn't bank on it. They certainly have no place in an early stage startup.
