The vision of "one desktop, many devices" (https://www.divergent-desktop.org/blog/2026/01/26/a12web/#a1... ) seems perfect for cloud hyperscalers to own all of compute. Your desktop will be in the cloud, the only computer with enough CPU power and RAM to run your stuff, and you will be allowed to access your desktop from any device you license from the cloud hyperscaler.
