I couldn't disagree with this characterization more. They will need human intelligence overseeing the majority of the cases, and those that they try to automate will be fraught with difficulty and take a long time to iron out. Even the examples I've seen posted of people using it so far would not have been able to be automated and required extended conversations.
(And just in general stuff that is actually easy to automate will mean a ton of middle men already exist to make it easy, or more likely, the person could just do it themselves quickly)
The founders can either outsource to someone for as cheap as they can manage and target clients who don't care about likely significant middleman fees (and who are most likely on the lazy side), or they can spend all of their attention each day doing these little tasks for people.
Since it was a whimsical side project, as they described it, I imagine this will go on for a little while longer, but then they will wind it down and/or maybe try to sell it like the glitter envelope guy who didn't want to do all the work, and then have something quite nice for their resumes, plus some PR to go towards their next project.
