The article said that it was previously expected in ~2000 years, then mentioned that the rate is about 10x faster. Assuming (quite possibly erroneously) that the relationship is linear and both of these factoids are accurate, that puts the change on the order of ~200 years.
So it doesn't seem likely that most of us will live to see it. That said, I understood it to be a gradual process and I thought there was a time of little to no magnetic field while it's shifting, which might be disconcerting.
Hopefully it's just a matter of securing power lines and hardening satellites, but I'm not sure whether anyone has studied this in much depth.
