Generally really good points. However one great use of realtime analytics is as a way to immediately catch production errors (particularly when connected to alarms, e.g. Splunk). My thought is that realtime amazing systems as discussed can be an exceedingly difficult engineering problem or a trivial business problem (use google or another hosted solution). Personally, any engineer who would try to reinvent the wheel on this one (rather than leverage any of the many incredibly refined existing technologies) should not serve in a decision-making capacity.
