Advanced AI will make advances in economics, military, medicine, science, technology, etc occur far faster than we are used to.
There was more innovation in medicine and STEM in the 20th century than in the 1900 years before the 20th century. People may dispute that, but its accurate. The world of 2000 was far different from the world of 1900 when it came to science, technology and medicine.
In theory, radical advances in AI will do the same. We may see radical advances in much shorter time frames than we are used to. The time frame to go from 6th gen fighter jets to 7th gen fighter jets may take 30 years w/o AI. With advanced AI, it may only take 5-10 years (possibly less). So a nation with an inside track on AI will have a massive military and economic advantage over nations with less advanced AI. Hence why NATO nations are limiting computer chip shipments to China. A modern NATO nation would decimate the Nazis in WW2 because modern military technology is so much more advanced. Even modern Russia, which is struggling to defeat Ukraine, would decimate the Nazis because modern Russia has such more advanced technology than we had in the 1940s. Nazi planes would be shot out of the sky before they were anywhere near in range of enemy planes, and Nazi tanks would be destroyed easily. It would be like when the US went to war with Iraq in 1991 and the US destroyed thousands of Iraqi tanks in a few weeks.
Economies used to grow by 0.1% a year before the industrial revolution. Now developing nations can grow at 10% a year and developed nations grow at 2-3% a year. Economic growth rates 20-100x faster than they occurred pre-industrial revolution are common.
A nation that has advanced AI will see its military, economic and political influence dramatically grow globally. That is why there is a race between China and the US.
Before the industrial revolution, human society was mostly limited to biological muscle. The industrial revolution gave us machine made muscle and as a result we experienced rapid advances in STEM, medicine, economics, etc. When cognition is done by machines rather than biological tissue (which it has been up until recently) we will see another dramatic increase in the quality, quantity and speed of advances in STEM, medicine, economics, etc.
Also even if we are in a stock bubble, even when the bubble pops, AI will still advance. Current AI may not, in the near term, be able to deliver the economic growth that people are expecting and AI stocks may tank. But that doesn’t change the fact that AI itself will keep advancing, the same way the internet kept advancing after the dot-com bubble burst.
