TWTs are going to be around for a long time. There are only a handful of companies in the world that make them, and there are no real alternatives to producing high power microwave signals.

There are also IOTs, klystrons, and BWOs, and their cousins from the gyrotron side of the family. There's a lot of territory for solid-state devices to conquer before vacuum tubes are obsolete, and solid-state devices can't even operate in most of those regions, let alone outperform vacuum tubes.
