However, our little museum run with volunteers and pocket change managed to be more stable long term than the well-healed and well-funded Living Computer Museum. Why? Because having a single benefactor for a non-profit is almost a death sentence. It's super risky, and as we've seen here, when that single donor goes away, it's all over.
It's super sad the LCM is in the state it is in, but for non-profits this is a cautionary tale: you cannot build a long term non-profit on the support of a single person. The world is too chaotic for that. Even a non-profit with a billionaire behind it isn't safe. It is incredibly poor planning on humanity's part to rely on the rich to preserve our shared heritage out of some obligation or moral or ethical duty. We need to preserve this stuff on the order of the Smithsonian.
