I would agree with most of this except for the establishment of the technocracy. I do not think Mao or the gang of four wanted to establish a technocracy. That is a bit different from the aim of the cultural revolution, which was hostile towards the academic class and the Western style of academia (Bach was targeted just as Confucious and Mengzi).
A side product of the revolution and the departure of the Gang of Four, together with Mao's death, led to a power vacuum. This was filled a few years later when Deng Xiaoping and his supporters gained prominence. Deng Xiaoping was the true technocrat, and his reaction against the cultural revolution is what paved the way for today's technocracy. Now the question of whether Deng Xiaoping is spinning faster in his grave than Mao is open for debate.
