contemplating dark matter and energy

A few centuries ago, mankind knew nothing about many types of matter and
energy which we now understand, and which have given us great powers, for
good or bad.

So, at this time we know very little about dark matter and energy and models
about them are necessarily simple- but, isn't it likely that they are
actually very complex in structure and that when we do understand them
better we'll gain immense new powers?

I should think science fiction writers could have a field day speculating on
this- are they doing so? I haven't read sci fi in decades so I don't know
what the best are doing.

Just fantasizing, but I can imagine future being very impacted by better
understand of this stuff and not just the science of astronomy.
