There's likely to be very little funding for GLSL moving forward, and I would expect no major spec updates ever again, but vendors will probably keep publishing extensions for new GPU features and fixing things up. GLSL still has a fairly large user base. Whether SPIR-V is going to be the only Khronos shading language (or whatever you want to call it) moving forward, that's hard to say. Nvidia is pushing for Slang as a Khronos standard at the moment. Not sure if anyone's biting.
