If you look at the life efforts and accomplishments of the ~100 billion humans who have ever lived, how many lifetimes would you discount as having "non-human intelligence" based on the lack of "novel" contributions to frontier of our species' scientific understanding according to the same high bar you apply to LLMs?
Do you pass that bar yourself?
Ordinary humans do novel things all the time. Where do you think LLMs got all the training data that their responses come from?
