The even bigger problem is that current quantum computers, if indeed they are, are not heading down the universal quantum computer route, but instead heading down the route of adiabatic quantum annealing. I mean if you can explain that to your kids, could you explain it to me? I would take issue with various claims in the comic anway. The idea that quantum mechanics is a "generalisation of probability" is itself a simplification. The wave function can be used to derive the probability P=Ψ.Ψ*, but it's not probability per se. It does neatly encapsulate why the Copenhagen Interpretation of the wavefunction leads to a lot of magical thinking about what the wave function represents.
