Yeah, I don't think SMT is going away. It's one of the tricks CPU vendors have to eke out more performance, now that they can no longer significantly boost clock rates and shrink die sizes. So we will still have supercomputers and such with this technology enabled, but they will be air-gapped and acoustically isolated, or maybe just have their network perimeters beefed up. And then for mission-critical, sensitive server loads SMT will be disabled (or they will use SMTless CPUs).
