It’s trivial to achieve under 100ms in the US with even just one server.
Most companies aren’t international.

Barring the interactivity SPAs will also end up talking to server anyway. So even SPAs will feel sluggish in a high latency env.
I’d rather have sluggish UI with proper feedback than potentially inconsistent states which I often experience with modern SPAs. At least that represents reality. Just today I was posting an ad on the local classifieds page, and the visual (client) state convinced me that everything was fast and my photos are uploaded. Turned out all state was lost and never reached the server, and I had to redo everything again.
