The benefit is that you can allocate arbitrary computers to compute arbitrary things. As it is now, you have to use kubernetes and it's a comedy. Though perhaps the same in effect, there are dozens of layers of abstraction that will forever sting you.

You're thinking from the perspective of the terminal user—ie, a drooling, barely-conscious human trying to grasp syntax and legal oddities of long-dead humans. Instead you need to think from the perspective of a star trek captain. Presumably they aren't manually slinging sql queries. Such tasks are best automated. We are all the drooling terminal user in the end, but plan9 enabled you to at least pretend to be competent.
