The military will still get it's $1.5T+ budget tho. There's always enough money for more bombs.

In Western culture we tend to define ourselves based on our job, aka our economic output. That person is a fireman. That person is a doctor, or programmer, or whatever. As such, we are nowhere near ready for a world in which AI does all the knowledge-based work and leaves humans with nothing but manual labor. You* need to realize that your life never had any more meaning than that of the grocery bagger, or the ditch digger, or the vagrant, or even the criminal.

*the general "you", not you specifically.

Just like with a video game, just because the cheat mode exists, doesn't mean you have to use it. I suggest you do things you enjoy doing, and not worry about what value other people may or may not see in the results. Some people get great satisfaction from creating sand sculptures, while always knowing the work will be destroyed in a matter of days, or even hours. Take pleasure in the act, rather than the result.

There are plenty of people who do not accept this.

We had to outlaw child labor because lots of people thought children should work. Students are shamed for taking on debt to pay for their schooling. People think they should have to work their way through school. Retirement is coming to be seen as a luxury. A great deal of jobs in America don't provide any kind of parental leave, so clearly some people think new parents should work. Same thing with sick leave. People go to work sick every day because that's what the system demands of them.

The only category that is even close is disabled people, but even then it's not universal. Goodwill thinks disabled people should work, and they have a legal exemption from minimum wage so they can employ them. There are also lots of people think the disabled should just be exterminated because they can't work.
