> the remaining piece is either to extend QED/QCD to accelerating frames of reference or to quantize general relativity
Quantum field theory in accelerating frames of reference is old hat; poster children like the Unruh effect [1] and Hawking radiation [2] are from the 1970s.
Saving the ozone layer required changing practices in a relatively small part of the economy (refrigeration, mostly). In 1994, the total cost of the transition in the US was estimated to less than $100 billion [1], about 1.3% of GDP ($7.3 trillion [2]).
Reducing global carbon emissions to reach net zero by 2050 has been estimated to cost $9.2 trillion per year [3]. World GDP is currently $126 trillion [4]. That means 7.3% of current world GDP per year, or 1.8x of it over a quarter century.
> If the króna fluctuates so much, wouldn't that also indicate that demand for the króna just fluctuates a lot?
Yes, relative to the size of Iceland's economy. Average daily ISK turnover on the interbank market is only 4 or 5 million EUR [1]. A single commercial transaction, like the purchase of a new trawler from abroad, can easily be worth 2-3x that amount and cause the exchange rate to spike due to the lack of liquidity.
Aside: I used to love reading qz. Anyone remember when it was a chat/imessage style mobile app? The news was super short and quirky.
Then they sold out and most recently literally sold out to this software company from my neck of the woods. Every single article now feels like it's written by an LLM optimized to write like a crypto/AI bro.

Yes, and it (or at least one of them) has now been found. Maybe you don't care about knowledge for its own sake, but as the "irritating" press release goes on to point out,
“There are currently no treatments for what early-life stress does to the brain, partially because we have not had a clear picture of what molecular mechanisms to target,” Peña said. “This work is exciting because it reveals a clear mechanism, and also helps explain why the impact of stress is both latent and broad.
government, where two thirds of spending comprises transfer payments that help households bridge the gap between their spending, retirement, and health care needs and their wages and salaries [1]
The market comment linked in the paragraph above that one features a toy model of the US economy which illustrates this (section "Equilibrium in output and income"). [2]
