Things may slow down but they won't come to a screeching halt. So instead of running off to a legacy at 1500 TurbPIC now you'll have to have 3-4000. Once you get there instead of upgrading in 6-8 years now it will be 8-12. The bottom line is that a fraction will chose to work past 60 and be able to. I just don't think (in my opinion) that it will have that much effect, some but not as much as most are saying.
