Well, they managed to pull about a billion people out of poverty over the last 4 decades or so, which means that mainly they were following leftwing ideals.
(I come from a country which had actual Fascism until the 70s and what the Fascists did was the exact opposite of that: the vast majority of people were dirt poor and kept dirt poor whilst a tiny elite tightly interwined with the Fascist Government gorged themselves on the wealth of the country).
However, it’s been some time since China did that lifting of the masses out of poverty, and they’ve been shifting to Capitalism whilst keeping the Authorianism from their implementation of leftwing policies (they called it Communism, but they never really reached such utopical state, so I’m wary of calling that Communism).
Are they even left of center nowadays? I don’t know enough in detail how modern China operates to pass judgement on that - outside of China we mostly hear of what’s done in domains that reflect the part of their ideology that falls on the Libertarian-Authoritarian axis, not the stuff that falls on the Left-Right one.
I don’t think they’ve yet moved all the way to Fascism, though, even if they’ve kept the Authoritarianism going.
Before transistors there were vacuum tubes which did the same thing but using very different principles (and were also way bigger, even than traditional transistors and billions of times more than the transistors in the most modern ICs)
Before electric milling or even steam milling, flour used to be milled using watermills and windmills which, IMHO, are way cooler.
