It's just a matter of time at that point

> if we were to get there the entire world will be a different place; everything will have advanced so we won't be insuring our present world with our current knowledge and current tech but a future world with future knowledge and future tech

That's a very convoluted way to spell "famine, wars and mass immigration". Techno-solutionism has become a religion, you don't even have to understand or look at the problem, just repeat "tech will save us all, in tech we trust".

Not everything advances. We still have houses built in the 1800s/1900s that are usable in predictable/similar climates/circumstances. A changing climate changes that.

Sure, we could bulldoze everything and build new stuff that can handle a +2C, +3C, +4C, etc... world, but that's expensive.

Sounds super optimistic. Despite some efforts to mitigate climate change. Industrialists are hell-bent on removing regulations and consuming more power than ever. Cooling things is expensive and the laws of thermodynamics don't care about how advanced a society is.

"All natural and technological processes proceed in such a way That the availability of the remaining energy decreases In all energy exchanges, if no energy enters or leaves an isolated system The entropy of that system increases Energy continuously flows from being concentrated To becoming dispersed, spread out, wasted and useless New energy cannot be created and high grade energy is being destroyed An economy based on endless growth is Unsustainable"

We're up +1.5C already and it's a polynomial growth. This current figure was also on the "upper end" of projections from 25 years ago.
