I see Rust with a lot of potential, especially if/when it moves into domains like aerospace and other control of critical physical hardware. These are places where a reduction of bugs saves lives and/or huge amounts of money.

Machine learning definitely has potential, if we have another surge of breakthroughs in the future amazing things will become possible

Something I would like to see is a movement for software user rights. Between hardware that locks you into to the manufacturers store, and software that is constantly interrupting you and pushing ads at you instead of allowing you to do your work, some kind of social movement to push back against these UI dark patterns is sorely needed. Using computers is absolutely horrible compared to what it could be because of these issues.
