Sure, a lot of tasks won't exist anymore. I've seen many rote administrative tasks coded out of existence by very simple glue code as well, and some people may lose a job if they can't adapt. But the same could be said for many things. I've done manual memory management at the start of my career, working on plain applications. At this point it is coming back a bit due to popularity of Rust, but you'd mostly need to have an interest in systems or game programming in order to learn how to do it properly. The average web or application programmer really doesn't have to learn how to allocate memory and debug leaks, and may be in a lesser position to recognize and trace leaks in their buggy python or ruby code for it. But overall, it doesn't matter too much.
