This is probably controversial, but i always disliked how the Borg seemed to assimilate for the sake of assimilation? It was sometimes explained as their way of growth or achieving perfection, but that always rang a bit hollow as a motivation.
If I could write a longer term direction, it would be interesting as a quasi-justifiable thing; have the Borg be the boogeyman in the dark of space, until we find out its collective drive to assimilate is a way to insulate itself against some greater evil.
I’ve always liked stories of eldritch horrors lurking in the depths of space, so one way you could do this, is for there to be something lurking in subspace; warp drive weakens the fabric of space holding it back, which explains the Borg using transwarp conduite instead. This horror would be able to easily subvert individual minds to its needs, but the collective acting as a whole could resist it.
A “bad guy” doing bad things for an understandable reason is much more interesting that them just being straight-up evil. So in general I would aim for something like that.
I frequently amaze new colleagues when I show them that deploying an update for our backend application is a sub-second affair. Our pipeline keeps track of what git tag was deployed last, diffs between that tag and the new release, and uploads the files to each of the deployment targets. It takes longer for the pipeline agent to spin up from Cold on a Monday morning, than it does to actually deploy.
The core of the application is just php scripts, and those are either immediately up to date whenever the next call is, or swapped out the next time that component finishes a processing cycle.
Docker containers are nice, but nothing beats the cause of a stack trace being fixed, tested and deployed to the acceptance environment within minutes of it arriving.
