Tanenbaum was right, the future of the Linux kernel is dire, and it's been a huge setback to operating systems research in practical terms.

Fortunately, vendors are gradually moving away from Linux, having been hamstrung by its failures. Google is planning to move to a capability-based microkernel in the coming years for Android and ChromeOS, and Huawei has already done so with HarmonyOS.

In a hundred years, Linux will be a footnote in computing history.
