Probably embedded stuff. Web dev will probably die down, and with robots and automation and IoT becoming more prevalent, embedded programming will probably become popular. But hopefully by then embedded devices won't force us to us languages like C or C++. If the manufacture of embedded platforms scales up enough (more than it already has) then maybe we'll get devices with gigabytes of ram and insanely fast processors, so we can just write code in whatever language we like and have it be performant. A pipe dream maybe, but it wasn't that long ago that people were exclusively writing in assembler when performance was critical.
