You just can’t differentiate between a robot and the very best of humans.
I first read this book a long time ago, 10+ years, and I recently decided to read it again.

Wow, I was mind blown by this book one more time, it is absolutely crazy that Isaac Asimov managed to envision stories and concepts so far ahead of his time (Asimov wrote his first robot stories in 1939 and 1940).
And as I was reading the quote above, the recent “LaMDA incident“, comes to my mind. Are we there yet? Have we created our own version of the “positronic brain”? A form of consciousness recognizable to humans.
According to Asimov’s stories, we are a bit behind schedule. The positronic brain was invented on 1972 by Dr. Alfred J. Lanning. I guess we will have to keep waiting to have our own Robbie sitting by our side.
