My computer also can compute 5 + 5 and that is the opposite of real life in pretty much every way too. Not every algorithm results in life [and it requires algorithm + data + continual input, which the GoL doesn't integrate].
is a rejection of the idea that quantum computing allows any new problems to be solved
Because the idea quantum computing solves new problems has no basis in research or reality?
"Quantum" != magic
A tiny, currently impractical, factorization algorithm isn't a new problem current computers can't solve. They just take the long way 'round.
