A LFTR has already been run for years. A prototype was built at Oak
Ridge in the '50s as a research reactor prototype for the Air Force
proposal to have nuclear powered version of the B-36 that would stay
airborne almost continuously so as to be immune to a Soviet first
strike. But the project was dropped without ever being turned into a
power source. Part of the problem was that only enough shielding could
be carried to protect the crew, but the radiation also damages structure.

sodium fluoride is nonflammable. I am still betting on solar and wind
as cheaper and faster. I am thinking that getting this boy (LFTR) to
market will take the Chinese and Gates 20 years longer to get it all
to work correctly. Hence, even though I am a foul Trumpkin, I support
the quick and the modular, with batteries and, or,
micro-hydroelectric. It is something that dudes with a pickup truck
can install and maintain, distributed nationwide & worldwide.
Environmentally Safe!

A Liquid Fluoride Thorium Reactor (LFTR) would greatly reduce or
eliminate entirelythe 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.
I understand Indian is building a prototype LFTR. A molten salt
reactor is "walk away safe". Thorium also has the advantage that
there is enough already enough for millennia of power as a by product
of mining rare earths for magnets.

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."/

You didn't even mention what most scientist see as the big application
for QC, modeling and predicting the interaction of big biological
molecules, e.g. protein folding. One of the big motivators for QC way
Feynman's talk, "There's Always Room at the Bottom".
