You'd be absolutely correct if we knew how everything in nature works. We haven't explained everything that evolution has done and QC has been proposed for some of those things, for example the quantum mind hypothesis (where there are good arguments both for and against it).

In a way, your argument makes the same mistakes that it claims these scientists are making.

I'm not sure what you're arguing here; evolution has achieved this in the form of the human mind. I strongly doubt we are as close as some believe to creating SAI, certainly not in the lifetime of any living human being, but arguments that hinge on natural demonstrations require that this is eventually possible.
