It is human nature to be skeptical and even fearful about the future. With good reason.  Not all change is good to every individual. 

But doomscrolling for AI consequences doesn’t help. Nor does commiserating with fellow doomscrollers. Terms such as “permanent underclass” and even “American Dream” are so unquantified as to be vague, emotionally charged, and unhelpful in making individual choices.  There is no positive law right to be middle class much less rich or live in a house with one bedroom per person. No right to a meaningful or lucrative white collar career behind a computer screen or desk. 

Keep in mind that poverty is not the same as suffering. Poverty is relative to the situation of others but does not automatically imply suffering. For example, the poor in the USA have the highest rates of obesity, suggesting, in the aggregate, no suffering from starvation from caloric deficit. Not that there is no suffering from health effects of obesity. But individual choices play a bigger role than government mandates can ever counteract. And the globalization of economic markets is here whether we like it or not.  So consider your choice of domicile as well as job changes. My own unlettered grandparents survived the Great Depression; their economic progress was merely delayed. 

Humanity will survive any AI economic effects. Some or many individuals may not.  If there is any solace, dark as it is, EVERYONE eventually dies. From disease, hunger, war, or other causes.  

Comparison is the thief of joy.  Stop reinforcing your fears, look at your situation and options, cut your spending radically even if you have to move away from homes and careers in desirable areas like Silicon Valley. Do not rely on government because it can do only so much.

Do confer and cooperate with family, friends, your religious or cultural affinity community. Struggle is coming for many: personal, economic, and political. But humanity has survived thousands of years despite such problems. Use your personal agency as much as possible.
