What about countries with political strife like Myanmar? We can't hope that 100% of countries all experience significant growth, fast enough to outstrip the impact of rising temperatures. There will be laggards stuck on low GDP. Also, a lot of these economies rely on outdoor work, widespread AC can't help with that.
If we get to the 3-4C warming scenarios, these countries will be terrible to live in, regardless of AC, and I won't blame them when they all try to escape to colder Europe.
