If we look at the way the universe behaves, quantum mechanics gives us fundamental, unavoidable indeterminacy, so that alternative histories of the universe can be assigned probability.

Sometimes the probabilities are very close to certainties, but they're never really certainties
Interpretation
What this quote means
The quote emphasizes that while some outcomes may seem almost guaranteed, there is always an element of uncertainty involved.
Murray Gell-Mann's quote reminds us that in the realm of probabilities, there are instances where certain outcomes appear almost inevitable; however, it is crucial to acknowledge that absolute certainties do not exist in reality. This highlights the importance of understanding that even in situations where we feel confident, the unpredictable nature of life and science means we must remain open to the possibility of unexpected results.

What is especially striking and remarkable is that in fundamental physics a beautiful or elegant theory is more likely to be right than a theory that is inelegant.

Einstein's theory of gravitation replaced Newton's, but apples did not suspend themselves in mid-air, pending the outcome. And humans evolved from apelike ancestors whether they did so by Darwin's proposed mechanism or by some other yet to be discovered.

Brains are tricky and adaptable organs. For all the 'neuroplasticity' allowing our brains to reconfigure themselves to the biases of our computers, we are just as neuroplastic in our ability to eventually recover and adapt.
