Coding is inherently difficult -- any tools even as basic as color highlighting/spell checking massively help understanding code in front of you. There isn't a hope this can replace any programmers but instead aid their workflow. I great example is simply refactoring code with SOLID after building a feature or fixing a bug -- a lot of this can be easily automated. Having a machine suggest and a human accept is a worthy trade off. Another similar example is the Google bot that presents search suggestions for you.

I don't think your concerns are well grounded.
