He is entertaining to listen to, but he wildly distorts everything.
YouTube is trying to limit its reputation for spreading misinformation, slaps on this disclaimer:
Climate changeThis is pointless. The talk is not even about climate.
Climate change refers to long-term shifts in temperatures and weather patterns, mainly caused by human activities, especially the burning of fossil fuels.
I think the disclaimer is misleading. Humans are increasing the CO2 in the atmosphere, and that is probably responsible for most of the recent global warming. But the climate has been changing for millions of years, and I am not sure what it means to be mainly caused by humans.
Here a company eager for quantum computers:
Rolls-Royce runs simulations of the computational fluid dynamics (CFD when designing a jet engine) of the engine. A modern jet engine is a spinning maw of blades pulling in air at hundreds of miles per hour. Understanding how air moves through the engine as the turbine spins thousands of times per second is no simple feat for even the most powerful classical computers. Today, Rolls-Royce engineers have to scale down the CFD models or accept a lower level of detail. The firm believes quantum computing could pave the way toward more powerful and accurate simulations.So it is doing simulations on Nvidia GPUs, like everyone else. There is no chance that those simulations will ever move to quantum computers.
Sadly, the quantum computers we have at our disposal in 2023 aren't up to the challenge. The most capable quantum computers used in research have just a few dozen qubits (quantum bits), and the results aren't particularly reliable.
