Something is missing here, why do batch jobs take 13 hours? If this thing was started on an old mainframe why isn't the downtime just 5 minutes at 3:39 AM?

Exactly how much data is getting processed?

Edit: Why does rebuilding take a decade or more? This is not a complex system. It doesn't need to solve any novel engineering challenges to operate efficiently. Article does not give much insight into why this particular task couldn't be fixed in 3 months.

The problem is that the full set of specifications accumulated over three decades of usage is exactly as complicated as the code that still runs.

Just wait 10 more years and hope AI can solve it.

In the meantime, people can't renew their driver's license at 3:36. So what? Is that a requirement?
