I personally believe in determinism and understand the basics of quantum mechanics, but don't see how any of it disproves that the universe is deterministic. Electrons cannot move change momentum or direction of momentum without an outside force, so its position cannot be changed without an outside force either. And if it does change, this should be predictable by the amount of energy and by the angle of the outside force. I don't think that a probability wave function shows randomness either. There should be reasons that electrons are more likely to exist at certain positions on a wave regardless of randomness.
Certainly if some sort of new determinism exists in the quantum mechanical world, then it is different from the classical determinism. Before QM, you have positions and velocities and knowing these at one time would determine all subsequent positions and velocities. In QM, we think that there is a unitary evolution, so if we knew the wavefunction at one time, we could calculate the wavefunction for all subsequent times. But, the problem is, we dont know for sure if this is true. In the standard Copenhagen interpretation you have wavefunction collapse during measurement which if true would destroy even this version of determinism. Most sane people accept Copenhagen as operational way to derive experimental consequences from quantum laws, but equally sane people think that ultimately the evolution is deterministic in the quantum mechanical sense.
Then there is the classical dynamical chaos theory which were developed in the 1950-1970 time frame by Anosov, Kolmogorov, Sinai, and Arnold and others, this is the butterflies-wings idea which you may have heard of. It removes the possibility of even classical determinism as a useful idea.
So determinism is dead, but will not die completely.
