Yeah, this is the case for most legacy systems. The work to bring them
forward costs too much for the gain but you can't turn them off because they
do work that must get done. It's just that they and everything that touches
them tends to be in stasis.

After working with large data sets at Disney I can tell you that most coders
don't understand large amounts of data.

I recall a vendor that asked us for a test data feed and we sent them one.
Their response was they didn't want to have to build a new system to handle
this much data, could we please have a much smaller sample.

We had sent them a day's worth of data.
