You view on timeline is too short. We're not talking about keeping something online for 7 years, but for 70. If I had followed your advice a few years ago, I would have deployed on Geocities. Do you know what happened to those websites?
The question is, is wordpress going to be around in 70 years? No one knows. But that static HTML page will still render fine, even if it is running in a backward compatibility mode on your neurolink interface.
