> it's a net positive to have a technocratic state, deferring decision making to those with the technical skills to do it.

Deferring to the technical experts is great when you want to know how to do something.

Deferring to them when you're deciding what to do is not necessarily as good.

That's one interpretation. Other one is that a technocracy regime is done IRL to push highly biased and ideological policies on the guise of being the only/best choice by the experts.
