Agreed, and to add to the second point, in order to build it we must first understand it, although there is a chance to stumble upon it, but LLMs have already shown they are nothing like biological brains. One example is how brains use spatial-temporal mapping in the hippocampus or wherever, and it uses that as a database of sorts. We don't know if the features of the brain are necessary for actual intelligence yet. They may or may not be but chances are evolution took the shortcut and that intelligence is not easy to recreate unless taking this biological approach.
