Like dismissing a brand new product prototype as being unlikely to be a big success, this is a very low-value comment, in that it can't be tested in the short term, and the penalty for being wrong in the long term is zero. So you can comfortably make this sneer about every new medical innovation you hear about, losing nothing for being wrong but crediting yourself with intuitive powers if you're right, which you likely will be some day, the more so the more you repeat the move. That said, for every scandal like Theranos, the likelihood of another one just like it diminishes (if regulators and investors are acting effectively and rationally), so it might be a while before your prediction comes up. Let's hope so!
