DARPA wants to build a computer that mimics the human brain. 
At the same time scientists have shown that it is possible to reconstruct thoughts more accurately than ever before by analysing MRI images of the brain (along with the use of an elegant mathematical model). 
In some years we will be able to see what one thinks in his brain.
And then we will be “sure” that we know that mind and brain is the same.
But we will be wrong.
Take a TV.
Assuptions, assumptions, assumptions… !!!
