A government is a government. It doesn't matter who is in charge. What matters is how much the system facilitates negotiation.
I have heard people say that the ideal political system is one with a single benevolent and immortal dictator , but those people are wrong. Dictatorships don't respect citizens. It doesn't matter who is in charge.
A technocratic model sounds like a really fancy dictatorship. Have I misunderstood your proposal?
