Is it possible that someday every job in the world will be completely automated by AI?
Assuming you accept human-level intelligence is possible in classical computers, there is no job that could not theoretically be automated to the quality that it can be performed by humans, except jobs that specifically require that the worker to be human. For example, you need humans to have a restaurant with human servers. Or, to sell a book by a human author, it needs to have been written by a human. This isn't to say that there is any book that could be written by a human, or any task involved in being a server at a restaurant, that could not in theory be accomplished by a robot controlled by a program running on a classical computer.

Additionally, it is important to have legal persons sign-off on the result of critical decisionmaking systems so someone with legal personhood is liable if there is a negligence. Systems other than homo sapiens sapiens may be granted legal personhood at some point in the future, but for now, generally only homo sapiens sapiens get full legal personhood, and no programs running on classical computers have any sort of legal personhood. Areas where this human touch can be required include law and medicine. In the longer run, even the quality assurance step in this process could in theory be automated to be above human level performance, but regulation could mandate that a legal person give the final signoff, even if it has become unnecessary from a technical perspective. Because of this, even if the number of available jobs in these fields shrinks due to automation, there will be at least some jobs in these fields reserved for legal persons for the forseeable future.

Noone should feel like they are entirely safe from their job being disrupted by automation, though there is wide variation in how soon automation is expected to disrupt different professions depending on what kinds of tasks they are comprised of.
What solutions do you foresee for those people that will lose their job because of AI automation?
That’s a very important and challenging question. There is no easy or definitive answer, but different studies and experts have proposed different solutions and strategies to mitigate the negative effects of job loss due to AI automation. Some of them are:

Reskilling workers for new jobs that require human skills and creativity that AI cannot replace. This could involve providing education, training, and career guidance to help workers transition to new roles and industries.
Wage insurance and health insurance subsidies for workers who are displaced by automation and have to take lower-paying jobs or face unemployment. This could help workers maintain their income and well-being while they look for new opportunities or retrain for new skills.
Universal basic income (UBI), a form of social security that provides a regular and unconditional payment to every citizen regardless of their income or employment status. This could reduce poverty, inequality, and insecurity caused by automation, and also encourage entrepreneurship, innovation, and social contribution.
These are some of the possible solutions that have been suggested by various sources. However, they also have their own challenges, costs, and trade-offs. For example, reskilling may not be feasible or effective for all workers, wage insurance may not cover the full extent of income loss or job insecurity, and UBI may not be affordable or sustainable without raising taxes or cutting other public services. What do you think of these solutions? 🤔
