With all theories being to some extent “tentative” it should at this early point in time be no problem to where need be take “HTM” right out of TBT. You may have already seen my somewhat related reply to Matt for the last hangout.
There only needs to somewhere in the cortical mass be found the whole bunch of smaller brains with a moving straw views of the outside world. In fact I was quietly hoping that the theory would end up needing to include at least some of the individual neurons. In that case TBT only becomes even more awesome.
