I think Megafauna provides a useful hint (metaphor) about how we look at a quantum mechanical world, and the problems that might arise as a result.
We commonly speak of quantum behaviour in terms of 'particle' like behaviour, and 'wave' like behaviour, and get ourselves in a state of confusion when paradoxes seemingly arise.
But if you confine yourself to the mathematics there is no confusion. The confusion is an artefact of trying to explain the quantum behaviour in terms of our Newtonian world.
'Something', and 'Nothing', in my mind, falls into the same category - trying to understand a concept from a Newtonian point of view. The words something, and nothing probably have less (no) meaning in a quantum world.
This, of course, is all terribly esoteric. But it doesn't mean it has no relevance to our daily lives. After all, for example, GPS only works when relativistic corrections are made to Newtonian calculations, the semiconductor devices in our computing devices work according to quantum laws, and even the firing of neurons in our brains are thought to be influenced by quantum probabilities.
We are indeed lucky that there are capable people who spend their life trying to understand the world we live in. We are all much better off because of their passion.
