I'm really curious to what people plan on doing with such insane amounts of ram.

Maybe it's possible to scale with just RAM! Fire up a uWSGI + Flask and up the RAM as traffic increases.

database servers, redis and memcached I'm guessing. All of which are basically designed to take a memory-time tradeoff.

Yes, this is what I use my high-memory servers for. Giant memcached and redis slabs.

You can run a memory-based DBMS. That will easily eat all the RAM you can throw at it.
