We believe things are probabilistic, but we don't know it is so. To the best of our ability to measure it looks that way. I don't think we can say any more than that.

I am not denying that the transistor is useful and that science does useful things.

I believe a "successful theory" is one that should produce provably good predictions. Quantum computing cannot prove it works yet despite having made promises for a long time.

But you're right, I'm not a scientist, and anyone reading this should know that.

I will change my opinion on quantum stuff when we find it produces unfalsifiable quantum computing results that factor products of large prime numbers (or whatever else they promise to do). But as of right now I believe there is something wrong in quantum computing.
