I think that Sortition might be viable for an upper chamber of a bicameral legislature. Basically the (proportionally) representatively elected career politicians in the lower chamber would become experts at law making, and build up reputations and relationships with the public and each other, but any law they proposed would have to get through the screening process of a chamber of "ordinary" people. By not allowing the upper chamber to draft its own proposed legislation, there would be less risk of them falling into some populist mania and pushing through some half-baked idea that was trending on Twitter.
