This is the central flaw in the argument.  As people's
current skill set becomes non-marketable, people eventually
tend to acquire marketable skills to replace them.  (Yes,
there are some who never do.  Those retire, while new
workers who start off with marketable skills come in to the
market.  The advent of extreme longevity may skew this,
because older workers will have less incentive to retire,
and thus are more likely to eventually acquire marketable
skills; indeed, this effect can already be observed, even
with today's relatively modest lifespan increases.)
