I wonder just what sort of "digital" implementation they are compaing to,
e.g. a computer, programmable logic like Xylinx, a custom built system, or
what? I suspect some sort of unfair comparison, like a computer system
complete with peripherals.

What I thought was curious here was the complete lack of programmability in
their implementation. With some attention to programmability, they could
have made a much more flexible system.

Full employment can be had with the stoke of a pen. Simply institute a six
hour workday. That will easily create enough new jobs to bring back full
employment.
