I do not understand what you find convincing about this that changes your mind. We have a closed system that we designed to operate in a way that is similar to our limited understanding of how a portion of the brain works, based on how we would model that part of the brain if it had to traverse an nth-dimensional array. We have loosely observed it working in a way that could roughly be defined as similar to our limited understanding of how a portion of the brain works given that limitation that we know is not true of the human brain, with a fairly low confidence level. Even if you put an extreme level of faith into those very subpar conclusions and take them to be rigid... That does not make it actually similar to the human brain, or any kind of brain at all.
