There's a cutoff built into browsers in the form of a KeepAliveTimeout. A longer load time could have a valid reason, that's not for search engines to decide.

Also your example of a year is obtuse. It's like saying you should drive BMW because you will get killed in a Tesla if you crash at a million mph.

What Google's page speed factor does is differentiate between 1.5 and 2.5 seconds loading time. That has nothing to do with the quality of a page.
