Due to severe brain damage

you are only able to learn one programming language ever.

Which one do you pick?

C is still more wisely used by a huge margin. Just because you "enterprise" developers don't use it (despite the infrastructure of your managed languages being written in C and C++) doesn't change that.

Within a generation, it'll be in the same class as FORTRAN - only used to support legacy apps.

Yeah right. What are you going to write your kernels in? What are you going to use for those millions if not billions of microcontrollers that will still be in use that can't run a JVM? What exactly are you going to write your VMs and interpreters in? Right, they will have to be written in a C or C++ and assembly.
