Replying to Weight + stability for skis

i understand the advancements in boots with technology to make it more progressive/sturdier flex for lightweight touring boots. Bindings are just getting better with materials + creative designs. But with weight for skis, it seems like one of the best ways to make skis more stable. All these lightweight touring skis turn to vibrators when straightlining or very rough conditions, feel like that's not something we can fix with better materials. Will we ever reach something better? Thoughts?
