According to my understanding, Paul meant to say that with good scalable SMP support when you have 4 cores (often even 2 cores) the CPU scheduling algorithm have negligible effect on desktop responsiveness.
Same with memory - when an average desktop has >1GB in place kernel developers would rather not spend their precious time fine-tuning swapping vs disk cache.

It seems to me that when mighty 4-core, 2GB desktop feels slow in most cases you want to blame either slow disk or crappy application design rather than "kernel overtuned for enterprise".
