I can see their point but don't believe 100% of it.

Roll back to, say, 1985 when huge energy consuming Mainframes ruled IT... PCs that were connected and servers were not really around. In order to have any kind of application, (Payroll, AR, AP, etc) you had to spend quite a bit of $$ and have a decent amount of knowledge to implement this. Fast foward to today with the world of PCs and servers... in a matter of a couple of hours you can have a Windows server and an application installed and be connected to it via a URL. AND one person can basically do this. Way back when you'd have to spend quite a bit of money to get a Mainframe up and running in a controlled environment and several folks would be involved to do this same thing and it would take more than a couple of hours.
