The general pattern of argument I think is bogus is:

The brain has property X, which seems to be important to how it functions. We don’t know how to make AI’s with property X. It took evolution a long time to make brains have property X. This is reason to think TAI is not near.

As argued above, if TAI (transformative AI) is near, there should still be many X which are important to how the brain functions, which we don’t know how to reproduce in AI, and which it took evolution a long time to produce. So rattling off a bunch of X’s is basically zero evidence against TAI being near.
