Openness to technology use and to technological progress is a separate axis. The whole left-right thing is a convenient grouping mechanism and doesn't have explanatory power. If you dissolve it into multiple axes (openness to tech, authority beliefs/morals/economics, tradition, etc) you can show much tighter groups of beliefs with more distinct boundaries, but in practice they are lumped into "left" or "right" at a given moment, even though some of those clusters have switched from one side to the other (and even back!) in living memory. See also "horseshoe theory", which is what happens when you try really hard to put everyone on a single axis.

In contrast, populism is a style, not a set of beliefs.
