In terms of SpaceX (the space portion of it) they've produced the cheapest way to get any payload into space. If you pay anybody else, you will overpay drastically depending on who you want to take your payload into space.
In terms of AI, we've seen even here on HN everything from mathematical problems that remaind unsolved, being solved, mathematical proofs being used to disprove theories, heck we even learned more about alzheimers, new antibiotics, precision targeting in oncology, using AI to flag healthcare anomalies in imaging. The benefits are easy to miss, but they're snowballing into place, there's definitely an explosion of useless crap, but you have to look for the real things and you will come to find, that AI is giving us things we otherwise either might not have discovered or wouldn't have within our lifetimes.
