Has Networking Become Less Important?

I go to a non-target state school, and, like all non-targets, have been told to network relentlessly to be able to break in to IB. Since I go to a state school, networking has been tough since we do not have a very strong alumni base on the street and most bankers ignore my cold emails due to lack of prestige. I have not made many strong connections at banks yet, due to this fact. Finally I said screw it, and applied to a large BB (think GS/JPM/MS) online without having a single contact there. Within almost 24 hours I received an email back inviting me to do a HireVue. My question is, do you guys think networking matters less now than it did 10 years ago if you have a very good GPA since most banks now use websites and filter out candidates through certain criteria like that? Or did I just get lucky? Looking forward to hearing your thoughts.
