A Liquid Fluoride Thorium Reactor (LFTR) would greatly reduce or eliminate 
entirely the problems associated with conventional fission reactors; they need 
some additional research and development before they become practical but 
vastly less than what would be required for a fusion reactor.

Stalin and Mao Zedong had nuclear weapons and both were monsters, but neither 
of them ever used one in anger, the fact is the only human being who ever did 
was Harry Truman, and that was nearly 80 years ago. So I think the human race 
has a pretty good chance of surviving Putin and Xi.

Quantum Computers are well known for their code breaking abilities but that's 
not all they can do, in the June 9 2022 issue of the journal Science 
researchers report they have found a quantum learning algorithm that achieves 
an exponential speed increase over the that of any known conventional algorithm 
both in predicting how a quantum system, for example an atom or a molecule, 
changes over time, and also in its ability to extract useful information from 
noisy input data. It perhaps should be noted that a brain frozen to liquid 
nitrogen temperatures is bound to contain a lot of noisy data regardless of how 
carefully it was frozen. This is the abstract of the article:
"Quantum technology promises to revolutionize how we learn about the physical 
world. An experiment that processes quantum data with a quantum computer could 
have substantial advantages over conventional experiments in which quantum 
states are measured and outcomes are processed with a classical computer. We 
proved that quantum machines could learn from exponentially fewer experiments 
than the number required by conventional experiments. This exponential 
advantage is shown for predicting properties of physical systems, performing 
quantum principal component analysis, and learning about physical dynamics. 
Furthermore, the quantum resources needed for achieving an exponential 
advantage are quite modest in some cases. Conducting experiments with 40 
superconducting qubits and 1300 quantum gates, we demonstrated that a 
substantial quantum advantage is possible with today’s quantum processors."
