I can't see how having to support the network infra for 25k students' Netflix addiction is possibly a cost savings.

IT is more than internet connections. It's also, for instance, reducing your need for employees by having class registration done entirely online.

I definitely see the potential for cost savings in some areas, but there are whole sectors of technology activity in a contemporary university that aren't offsetting some pre-digital expense; they're just a reflection of the increased technical cost of instruction and lifestyle.

Yeah, but the cost of manipulating and transporting information approaches zero over time.
