The question in the title can only be answered by humans. No institution, no law, your regulators, or other disasters. Humans must working together, than they can keep Bitcoin maybe alive “forever” (I cant imagine infinity, and I wont live that long). It probably started with human activity, even though CZ said that Bitcoin was invented by an AI from the future. And in the end, it will also be controlled by humans. So far, nothing has been stop Bitcoin, and I believe that will continue in the future.
CZ is having a lot of fun this days, Bitcoin wasn't even invented, it was a creation of different investions. Bitcoin uses hash functions, it was already a creation, it used scripts which are already an invention, it used encryption which was already an invention.
Bitcoin is rather a creative work of a smart man and that man is Satoshi Nakomoto. I also don't agree with the AI thing else I'm not sure if we are going to be looking for a solution for quantum solutions without compromising the network.
