Thing is, shared hosting providers have offered web app installers like Installatron, Softaculous and Fantastico for many years. They allow users to visually install web apps but are still difficult to use and require lots of maintenance.

I think a radically different approach is needed, one that emphasizes real end-user value and data over APIs and tech. Something that's driven by deep UX design and can follow ordinary people throughout their lives without requiring them to become admins or worry too much about security and privacy.
