Many years ago when I was starting my work on human brain functions I was totally uncertain if I will ever succeed. So difficult and impossible cracking the human brain seemed to me. There was self-doubt everywhere in my brain.
But as years passed by I gained more and more confidence in my work and my doubts started receding. Then one day I finally realized I have the SOLUTION and I was completely sure now I know how the human brain is working. That was the time my self-doubts disappeared for ever.
That's how it works in every inventor's brain, that's why the world keeps rolling forward and that's why we now have real artificial intelligence in the form of working human brain simulation.
Why not to grant the same time to robotic beings?
