    1) Robots can't totally replace humans.
    Robots can't totally substitute for humans.
    3) Humans can't be totally substituted by r
    4) Humans can't be totally substituted with robots.

    Re: replace/substitute for

    1) is the best sentence.
    2) is OK and means, more or less, the same.
    I don't like 3) at all. I think it should read, 'Humans can't be totally substituted for by robots' and I don't like that any better.
    I don't think 4) has the intended meaning. It says that we can't do it, not that the robots aren't as good as humans.
