Yes, indeed. There is no such thing as "backpropagation" in the brain. The modern algorithm called "Neural Networks" has nothing to do with the 1940s model of the brain called the "Neural Network" model. The modern algorithm is a supervised optimisation process which approximates functions using a piece-wise linear regression model. Nothing about that algorithm, nor the function-approximations it produces, is based on anything in the brain. It's a bit like saying the Tesla was inspired by horses.
