There are 2 things that are orthogonal in current trend. This SSR buzz is not actually selling Server Side Rendering, they are selling 'one language to rule them all' (they call this dumb name "isomorphic").
Therefore, they are not solving all the problems of client-server + best UX constraints. Basically the problems we have all this time comes from:
1) There's a long physical distance between client and server
2) Resource and its authorization have to be on server.
2) There's the need for fast interaction so some copy of data and optimistic logic need to be on client.
The "isomorphic" reusable code doesn't solve [latency + chatty + consistent data] VS [fast interaction + bloat client + inconsistent data] trade-off. At this point I don't know why they think that is innovation.
