You forgot the (/s) I hope ?
This is just about geometry...

So if you were ridiculously reckless and wielded enormous power, you could try to reduce Earth axial tilt so that there are no more seasons. Problem : this also makes the equator even hotter and poles even colder.
(With even more effort you could try to increase the tilt even more, I'm not certain about all the implications, but it seems to roughly swap equator and poles ??)
Without that kind of (did I mention reckless ?) power, our future instead seems to be of the opposite of what you are asking for : in a bad case scenario, we might end up the current Ice Age (that we lived in for the last 2.6 Ma, and which roughly corresponds to the oldest known tool industry that pretty much separates us from other animals), returning the Earth into its (more) normal state, which also involves the equators and maybe even the middle latitudes being uninhabitable for Humans and maybe even for mammals in general.
So we might face a bleak future where our descendants are trying to survive in weird jungles (?) of the Siberian coast and Antarctica, where, unlike the current jungles, summers are indeed "constant light and winters completely dark". I have some doubts about whether any civilizations can rise in these conditions...
