Not only that, they despise leftist movements that call modern China what it is. Revisionist.
They hate Khrushchev while embracing the same bankrupt ideology that he pushed, but only whoever it’s in one of the countries that currently claim to be socialist. The social imperialism of the USSR was replaced by the social imperialism of Deng’s China and that was a good thing in their mind.
I can’t speak to the superconducting potions of this comment, but the general computing information is mostly correct.
Switching losses are a result of capacitance in the circuit. These capacitances aren’t going anywhere in transistors made from semiconductors. Additionally, even when a transistor is on it has some resistance, which of course creates heat whenever a current moves through that transistor. Leakage current also generates waste heat.
I could see room temperature super conductors being useful as replacements for bus lines in a digital circuit, but this wouldn’t eliminate the heat in the circuit. Most of the heat is created in the transistor junctions, so the effect would be very minimal if even noticeable.
