I think that, more precisely, the maximum amount of work that can go
through a concrete system is a quantity independent of programmer design.
Nobody is arguing that increasing the quantity of threads will increase
work throughput in a machine with devices already at full capacity.
What is being argued is that, since "task" is one of the machine's
"devices" consumed to do work,
increasing the capacity for "tasks" increases the maximum amount of work
that can go through etc.
If there are free processors, free memory, free network bandwidth, free
storage bandwidth etc. etc. then doing more work concurrently will increase
work throughput.
