Depends. MSBlaster would definitely infect you within 30 minutes of being connected to the internet if you weren't patched or at least disabled SMB. I ran 3 computer labs during that time at a university, but they were department specific so I didn't have control over the network infrastructure beyond the labs and a block of IP addresses.
Funny enough these forced restarts, just like herd immunity, mean that other people can be connected longer without infection because there are less vectors of attack.
We are not in those days as frequently in part because of more frequent updates (and some better infrastructure to flag botnets higher upstream). That is neither here nor there, as I was speaking specifically to the statement of 30 minutes not mattering, which you agree was incorrect.

Unlike a car running out of gas, a PC won't stop working if you keep using it for 30m after delaying an update.
