I haven't used or experimented with Truss.

But from what I've seen, those automated AI  programs to collect information are training our clients to use DIY software, such as TurddoTax.  If the AI is asking a million questions, it is essentially the same thing as a DIY program.

If you want to train your clients to use DIY programs like TurddoTax, fine, use an IA program like that.  If you want to keep your client and provide good service, personally, I would avoid AI programs like that.
