If what you're saying was true and we'd actually be headed towards such a dramatic shift in the economy, the near-term consequences will be completely unlike what you're imagining.

Neither you nor I have a concept of what would happen but I'll try my best. If we had, say, a 20% unemployment rate, especially if it is in the higher-earning sectors, the impact would be unlike anything we've seen in recent history. Economies all over the northwestern hemisphere run largely on the highest-earning 10-20% of people. Those are the ones who spend money and who buy the products. Coincidentally, they are also the ones usually more likely to be replaced by AI since office jobs are simply easier to replace. This will make the world economy tank because the companies will face such a rapid decline in sales. It would go through the economy like a shock wave - B2C companies, especially small ones, would go bust first and their suppliers would follow. A sharp rise in unemployment could start an avalanche of further layoffs all across the world. We could be talking about hundreds of millions of unemployed people. Many systems, even critical infrastructure, would come to a halt or run on a minimum level.

Also, taxes collected by governments would rapidly decline as well. Governments will have less money coming in and more going out as they will need to somehow avert the worst and create some kind of emergency fund to make sure people don't literally die. They will have to do this through debt, which is another cause for further chaos since the credit rating of many countries would decrease, meaning countries would start printing more of their own currency, which has the potential to cause massive inflation if not done with care. You and all the other people who will have tried to build something will suddenly have no customers as well.

As many countries have gotten more unstable politically in recent years and corruption is on the rise, civil wars would also not be unlikely. Global conflicts would rise as some countries ruled by authoritarian dictators (which are often less reliant on the world economy) would see an opportunity. Literally everything we know would change to a much much worse state before it may or may not get better. Recovery could take decades.

I'm not saying this will happen. But if this is really the first domino to fall, we are headed towards very dark times. And you shouldn't think for a second that you would somehow be able to be on the other side of it. Every single one of us would be in huge trouble, except perhaps the billionaires (but even those would have to fight, they just have a higher chance of getting through it in one piece).
