Unfortunately, dictators don't care much about damage to it's economy as long as they continue to be in power. When they expand and occupy more land, they will look very good in their country's history book which is a huge motivation for dictators. That's the reason why nobody thought Putin would seriously consider invasion but he did. And China will definitely attack Taiwan when the timing is right. Even if a million people dies, Xi would still be considered a hero by most chinese people if he took back Taiwan.
It remains to be seen if the person I think you are referring to is a non-dictator. He said he would be a "dictator on day one", and he sure was, but then he somehow forgot to revert to non-dictator mode...
Regarding "crashing real estate": actually, most other countries would love to have built enough to bring down real estate prices. Being able to afford a place to live is good for most people! But of course, investing in real estate makes you interested into increasing the value of your property, so you're now incentivized to stop more real estate being built (and also to stop anything else that might decrease the value of your property - thus NIMBYism).
Russia is out of the AI race. That has been lost and there's no way to reverse it.
If Russia wouldn't have started a war, it could have focused on building huge datacenters. It has all the energy it would have needed, now all it can do with it is sell it to China for cheap.
