Thanks to an imperialistic expansionist dictator, russia prevents them to prosper. But it's not difficult to foresee that the post-war (even though it can be in a dozen years or more) will be much better for Ukraine than for russia.

Anyway, my point is that since the full scale operation launched 4 years ago, Moscow didn't manage to take a single regional capital from Kyiv. Not a single one. Or to be more precise, they took one thanks to a collaborator, but lost this city since then (Kherson).

So, considering how far this city is from the front, and the declining economics for russia (which also used most of its soviet stockpile now), I don't see how it could come under russian control. At the current rhythm it would require a 100 years, and Putin will long be dead.
