If anyone claims to really know the future, be suspicious. :-)
We can tell trends; one of them is that the STAR conferences are become more 'technical' over time, but not going away. That means companies are still investing, often heavily, in test.
Over the next ten years I expect to see the lines between dev and test blur a bit, and testers, in some cases, to do more DevOps like work - build automation and so on. Going away? Not any time soon!
