I expect to see more 'corporate' languages like Go and Hack. Languages designed explicitly for the 'massive software company' use case, with a focus on simplicity and readability.
We might even see languages targeted at company sizes. Like here is the A language for getting prototypes out the door and here is language B which is the one you port to after your company becomes a unicorn and wants to grow the engineering team size to the 1000s.
Less even than that. C is more used than Go, even today.

The future looks like better, more powerful libraries. You'll have 10x as much code, but you won't actually have to know 90% of it. (Until there's a library bug that matters to your program...)
The problem with visual programming is that it doesn't scale past the size of your display. We have been capable of data flow programming with a gui for over a decade, it just isn't a great way to program complex systems.
I expect there will be more code and more of it will be written in languages like go. The biggest constraint on programming is comprehending big code bases, and languages like Go help with that.
