Answer and Explanation:
Today's society is shaped and totally influenced by technological advances, which have efficiently improved our personal, economic, political and personal connections, facilitating very important processes for the establishment of efficient communities.
Technological advances have facilitated our form of communication, allowing us to access information much more quickly. In addition, this advance has optimized the population's health with the existence of increasingly specific and efficient machines, in addition to allowing an increasingly safe and fast movement and transportation.
Nevertheless, we can see a strong improvement process in the devices to which we are dependent. More and more efficient machines promote jobs, previously performed by human beings, more quickly and economically, promoting a strong automation of services. This has caused competition in the productive sectors and has caused many layoffs, but it has raised the speed and standardization of services like never before seen.
In this regard, we can conclude that technological advancement is very beneficial to our society, but it has caused social problems that must be compensated by public policies that promote technological advancement and the protection of the population.
