A brain is not capable of prediction anymore than it is capable of having knowledge. Only of a (mostly) whole human person (and some non human animals) with a (mostly) fully functioning nervous system including a brain can we say they are capable of predicting things or knowing things. To say otherwise is to commit the mereological fallacy, ascribing properties/attributes/capabilities to a part of a thing that can only (logically only) be applied to the whole thing. A brain divorced from a body is nothing more than lump of grey matter capable of nothing more then a few basic cellular processes and perhaps some low level nerve impulse transmission for a very short period of time. Brains also cannot learn, adapt, organize, or remember, dream, sleep, feel, etc. A brain cannot sense anything in the external world for it has no sense organs and no senses. Only a (mostly whole) human person and some non human animals can do any of these things. After all these years of philosophical discourse on the matter there are still no brains in vats running around telling us about their dreams and learning things and describing how they feel.
