Too much could happen in 100 years, so personally, unless your family or friends choose to keep it going and find their own friends and family to keep it going, all will die. Hundreds of thousands of domains were here yesterday but gone today.. either due to lose interest or the person died and no one knew how to keep it going or even cared. It is very likely that the major websites, such as Chase or Home Depot or Lowes or any of these types of business websites will be here to stay for as long as we do banking and use the Internet. There are some things that can be done for continuity, such as funding a bank account that is specifically linked to domains and then you'd just have to account for hosting and the domain. If you leave it in your Will, you could keep that bank account going if you don't have greedy family members. In this case, you can set your domain to auto-renew and set autopay for hosting and just make sure you account for the amount you might want to keep it going though this could get expensive. But unless there is a successor or someone who really is as passionate and cares about your project enough to keep it going, it is very unlikely that it will go on without you.
