Acceleration of information movement can have as 
one of its consequences a multiplicity of jobs for 
everybody. In fact, joblessness as the consequence 
of automation may well mean the end of the single 
job for the single lifetime, and the switchover to a 
multiplicity of jobs for every lifetime.
