One who knows the past, present, and future?
A complete understanding of the present – combined with the relativity of the passed – would make extremely accurate predictions possible.
The ‘ultimate mind’ could process and take in information at the ultimate speed.
The ‘singularity’ isn’t here yet – but if it was – you would then witness a the birth and evolution of ‘ultimate’ minds.
I wonder why, WJ deleted his post.
If I remembered it corrected.
The present is what we comment on, and the past we study, and the future is predictions and is not allowed to be known only for a god.
I wish to be a godlike or very close to god, this is why I propose the question.
the ultimate mind is the “I don’t”
-Imp
Highest mind is no mind. No separation. Non-dualism.
So don’t think about it! 
Mine of course
The ultimate mind is the one that knows all and still remains sane.
