We live in the shattered remains, badly reconstructed, of what a true operating system could be - we have some of the pieces (zfs, k8s, virtualization, scaling, failover, nixos, qubes) but imagine it all put together, orchestrated, carefully documented and tested by immense number of engineers. Ah, what could have been.
