Depends on what you would call "futuristic" - different people have different connotations with that term, so probably everyone will have a different image in mind.
Keep in mind though with cities like Astana, those are usually no more than playgrounds of autocratic despots (which are quite common in post-Soviet -Stan countries), with the "futuristic" part being the only one shown to Western visitors (that applies to Russia and China as well). The largest part of the population does not live in parts of the city like that at all, and you cannot possibly call some of those areas "futuristic", see for example this:
(This picture is from Atyrau on the Kazachi Caspian Sea coast, so not technically Astana; but you probably wouldn't need to look far to find similar in Astana)
Considering the extreme and growing degree of inequality that will probably define the near future, I'd say that makes these cities
very 'futuristic'.
