Solid state per se isn't getting better¹. Software simulation of tubes ("software state"?) is getting better, or has been (it may have plateaued).
Tubes are still the reference model.
All the DSP cores in a modern amp are just a cover band playing tube tones.

1. I mean other than digital solid-state getting more highly integrated and faster, to run more complex software. The necessary analog audio paths in a DSP system aren't getting better.
