Note that noone replied to Eric and the thread continued on. Also go back and read some of Linus's posts before this. Eric writes using vague generalizations about age and experience; Linus writes with specifics about his experience with the kernel. The former style makes for popularly read posts but the latter seems much more effective.
Also, compare this message from Linus earlier in that thread https://lkml.org/lkml/2000/8/22/52 with a post of his from yesterday: https://lkml.org/lkml/2014/2/10/575, especially regarding abstraction.
