In the near term, the goal of keeping AI’s impact on society beneficial motivates research in many areas, from economics and law to technical topics such as verification, validity, security and control Whereas it may

be little more than a minor nuisance if your laptop crashes or gets hacked, it becomes all the more important that an AI system does what you want it to do if it controls your car, your airplane, your pacemaker, your

automated trading system or your power grid Another short-term challenge is preventing a devastating arms race in lethal autonomous weapons

In the long term, an important question is what will happen if the quest for strong AI succeeds and an AI

system becomes better than humans at all cognitive tasks Such a system could potentially undergo recursive

self-improvement, triggering an intelligence explosion leaving human intellect far behind By inventing

revolutionary new technologies, such a superintelligence might help us eradicate war, disease, and poverty, and

so the creation of strong AI might be the biggest event in human history Some experts have expressed concern,

though, that it might also be the last, unless we learn to align the goals of the AI with ours before it becomes

superintelligent

There are some who question whether strong AI will ever be achieved, and others who insist that the

creation of superintelligent AI is guaranteed to be beneficial At FLI we recognize both of these possibilities, but also recognize the potential for an artificial intelligence system to intentionally or unintentionally cause great harm We believe research today will help us better prepare for and prevent such potentially negative

consequences in the future, thus enjoying the benefits of AI while avoiding pitfalls

Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to each of the questions

People are living longer and, in some parts of the world, healthier lives This represents one of the

crowning achievements of the last century, but also a significant challenge Longer lives must be planned for Societal aging may affect economic growth and lead to many other issues, including the sustainability of

families, the ability of states and communities to provide resources for older citizens, and international relations The Global Burden of Disease, a study conducted by the World Health Organization, predicts a very large increase in age-related chronic disease in all regions of the world Dealing with this will be a significant

challenge for all countries’ health services

Population aging is driven by declines in fertility and improvements in health and longevity In more

developed countries, falling fertility beginning in the early 1900’s has resulted in current levels being below the population replacement rate of two live births per woman Perhaps the most surprising demographic

development of the past 20 years has been the pace of fertility decline in many less developed countries In

2006, for example, the total fertility rate was at or below the replacement rate in 44 less developed countries One central issue for policymakers in regard to pension funds is the relationship between the official

retirement age and actual retirement age Over several decades in the latter part of the 20th century, many of the more developed nations lowered the official age at which people become fully entitled to public pension

benefits This was propelled by general economic conditions, changes in welfare philosophy, and private

pension trends Despite the recent trend toward increased workforce participation at older ages, a significant gap between official and actual ages of retirement persists This trend is emerging in rapidly aging developing countries as well Many countries already have taken steps towards much-needed reform of their old-age social

insurance programs One common reform has been to raise the age at which workers are eligible for full public

pension benefits Another strategy for bolstering economic security for older people has been to increase the contributions by workers Other measures to enhance income for older people include new financial instruments for private savings, tax incentives for individual retirement savings, and supplemental occupational pension plans

As life expectancy increases in most nations, so do the odds of different generations within a family

coexisting In more developed countries, this has manifested itself as the ‘beanpole family,’ a vertical extension

of family structure characterized by an increase in the number of living generations within a lineage and a decrease in the number of people within each generation As mortality rates continue to improve, more people

in their 50’s and 60’s will have surviving parents, aunts, and uncles Consequently, more children will know their grandparents and even their great-grandparents, especially their great-grandmothers There is no historical precedent for a majority of middle-aged and older adults having living parents
