Vocaloids were invented in 2000, with commercial release in 2004. Human singers aren't extinct yet.
It may be possible in the future for a synthetic voice to sound fully human with a full range of emotions. But I believe that human actors and voice actors will still be used because 1) it's easier to explain what to do to a human professional, 2) unions exist and they will push back against it.
Acting is an art. What world is it where robots do art while humans do the tedious manual labor?
Adding to all the reasons already listed, Russia isn't striving. For example, right now there is a number of towns and cities experiencing outages in central heating (with houses designed around central heating so basically no other option to heat their appartments) while the weather dips to -20°C (around -4°F). All because the centralized boiler facilities weren't properly maintained due to the lack of money (or, to be more precise, due to money being diverted towards the war).
There are other signs, like plains malfunctioning and flights getting delayed because some component broke and cannot be replaced due to sanctions, and they happen more and more often. Also the less noticeable stuff like prices of common goods increasing by a factor of two in the last couple of years while salaries barely increased at all.
So yeah, Russia is keeping itself afloat, but it isn't thriving at all
