You get used to it. Is it better than than waiting 54s? For me, yes, it's better to juggle a few sessions than stare at the wall while I wait.
Better to have my concentration split up among multiple tasks than to have it be completely broken while waiting for one of my agents to finish.
At least some cognition researchers think yes it is better to wait than to context switch.
Learning to just sit and "be bored" can train you to have stronger attention on one thing.
