You've missed the main point that the 'meaning' of the word 'university' is embedded in a transcendent discourse network about 'education' which is required to give meaning to any constituent parts of a university.
But I make two final points philosophical points.
two items are trivially both 'similar' and 'different'. They are similar in that they are objects of a comparison, and different because there are two of them.
2. The fact that we have separate words, 'mind' and 'brain' used in different discourse contexts, implies they are not isomorphic.
I do not intend to elaborate here on the specific scientific follies of reductionist materialism and its failure in the field of AI, since this thread is ostensibly about the religious aspects of 'self identity'. Neither of us, I suggest, has anything useful to say about that
