The laying on of scorn

Dan Crawford notes Paul Krugman’s change of heart on the increasing importance of automated systems, in particular robotics:

In the past discussions at Angry Bear on the impacts automation might have on our lives, and the economics involved, gathered comments such as “You are a neo luddite”. As if widespread use of automated systems was automatically good for us overall because we would have access to ‘more higher wage and higher skilled jobs’, cheaper goods, and robots need a work force to maintain them…of course, there was no offering of numbers of jobs and whether the wage premium for a college education would be maintained. This is the time to pay more attention as ‘insourcing’ gains traction as a buzz word…

Peter Frasure Robots and Liberalism, Sociology, CUNY Graduate Center responds, and offers a post as a lesson in scorn, and he was kind to me, tough with others:

What I mainly find interesting is what all this interest in technology and jobless growth says about the limits of contemporary liberalism. We can all hope that Gavin Mueller’s reverie of Paul Krugman dropping LSD and becoming a Marxist will come to pass, but in the meantime his type seems to have no real answer. Nor do those of a more labor-liberal bent, like Dan Crawford at Angry Bear, who laments being called a neo-luddite and scornfully says: “As if widespread use of automated systems was automatically good for us overall”. As if a world in which we hold back technical change in order to keep everyone locked into deadening jobs is a vision that will rally the masses to liberalism.

So exactly who is the man actually talking to??  What am I missing?
